Moms and dads are often overwhelmed with many different feelings the first time they hold their child after he or she has been born. After that, they usually find themselves worrying about pretty much everything.

For example, they are in a hurry to know their child's Apgar score. For those who do not know, this is a test that healthcare professionals give newborns. According to kidshealth.com, it checks their heart rate, as well as some other things.

Furthermore, they also want to know how their bundle of joy compares to other babies who are around the same age. Parents also ask themselves if their child is getting enough milk, or if he or she is opening their eyes at the right time in their life.

New parents usually want to know if their child is reaching all of the developmental milestones that they should be reaching and if they are doing it at the right time. Furthermore, they might even begin to feel some anxiety if they believe that something is not right with their baby. Also, many parents feel as though they are at a loss if they think their baby is not doing something that an article on the internet said that they should be doing.

Something they should know is that some delays are considered to be normal. There are a lot of external and internal factors that can affect when a child reaches a certain milestone. When it comes to a baby starting to crawl, and eventually walking, their parents want to know what they can do to encourage the child, or if they can do anything at all.

If a baby is not crawling when they should be, their parents might wonder why that's the case. They also might want to know what they can do to help, as well as what kind of things they should be worried about when it comes to their baby crawling.

There are some people who believe that crawling is not essential to a baby's development, but others believe that it is. There are normal reasons why a baby may not be crawling, and those are usually things parents do not need to worry about. However, there are also other reasons why children may not be crawling, many of which are definitely things parents should worry about.

15 Baby's Feet Are Curved Inward

via Scottishrightshospital.org

There are some things parents should be looking out for before the baby begins to crawl, and curved feet is one of them. In some cases, a baby may be born with feet that are slightly curved inwards.

As a result of being cramped in the womb, babies only begin stretching out gradually over the weeks and months that follow the birth. If natural extension does not happen by the time he is ready to roll on his belly, it can be discouraging for the baby, and it can impede the little one's regular movements, including the propensity to get up on his knees.

What parents can do: Parents can verify if their baby's curvature is within normal limits. Askdrsears.com suggests to do the following:

  • They can pick the baby's feet up and look at the soles. It’s normal for the front of the foot to be curved, so they do not need to worry if it is.
  • Then, they should hold the heel of the baby’s foot with one hand and gently stretch the front of the foot so that it is as straight as it can be.
  • If the foot straightens easily with gentle stretching, the curvature is considered normal and it will begin to correct itself within a few months.
  • To help the feet straighten, parents should continue doing those stretches with their little one whenever they are changing their diaper, and they should also ensure that the child does not sleep in the fetal position often.

If the baby's bones are flexible, the pediatrician will be able to gently pull the feet into a straight position. In more rare cases the bones can be rigid and may require additional therapy from an orthopedic pediatrician, or physical therapist.

14 Baby's Feet Are Too Flat

Another physical impediment that may delay baby's crawling and eventually getting up on his or her feet also has to do with the shape of the baby's foot. Flat feet in babies are more common than one would think, but they usually do not have flat feet for very long.

If a person's baby has flat feet, that can cause them to start crawling much later than babies who don't have flat feet, according to parenting.firstcry.com. One important thing parents might be relieved to find out is that children who have flat feet usually develop arches by the time they reach their third birthday.

What parents can do: Treatment is rarely needed except in the most severe cases, which a doctor will be able to identify. In most cases, children who have flat feet will actually have normal feet by the time they turn six, according to healthychildren.org.

But there are times when that does not happen, and parents might wonder if they should seek some form of treatment. Children will likely not receive any treatment for this unless their feet are stiff, or they are experiencing some pain. Furthermore, putting inserts in their shoes can end up causing more problems than what the child had to begin with.

But, not all flat feet are the same, and some of them do need some kind of treatment. For example, a child might experience a bit of tightness in their heel cord (which is referred to as the Achilles tendon), and that can put a limit on the amount of moving that particular foot can do. Also, some little ones might have rigid feet as well. This kind of thing can cause them a lot of pain, and sometimes it can keep them from moving their foot a certain way.

13 Not Enough Tummy Time

via Needpix.com

There are plenty of things parents need to know about tummy time, including the fact that it can help babies reach the crawling stage, according to zerotothree.org.

According to nytimes.com, it appears that children who do not spend much time on their stomachs have significantly weaker back and arm muscles than those who get plenty of time on their stomachs. That is because parents have started making their babies sleep on their backs since that puts them at less of a risk of developing SIDS.

Those who sleep on their stomachs are more likely to develop SIDS, which is why some parents might not lay their children on their stomachs. Since that is the case, there are many little ones who might skip the whole crawling stage altogether, and go straight to walking.

What parents can do: Moms and dads should keep their baby on its back during sleep time, but encourage as much time as possible on the tummy when the baby is awake. This is a great way to ensure their safety while helping them build the strength they need to crawl.

12 Baby Is A Non-Crawler

In light of the reduced tummy-time during sleep and naps parents are encouraged to practice, many babies go directly from scooting, or dragging themselves with their hands, to pulling themselves up when they are ready for further exploration. In addition to this, some babies are simply born as non-crawlers, according to todaysparent.com.

The reality is, although occupational therapists consider crawling a cornerstone of the baby's physical development, it is not really considered a milestone because not all babies crawl. Some people believe this phase is essential for the child's gross and fine motor development later in life, and that skipping this phase may cause certain delays in the future. In truth, it is only considered an issue after the baby has reached a certain age, and that is only when they also have not discovered other ways to move about when placed on a floor, according to kidsinthehouse.com.

This can be a stressful thing for parents during a time when there is already so much for them to worry about, but their pediatrician will only ask them to pursue further testing if a child is nearly 12 months and not attempting to either crawl or pull themselves up. Most doctors will be very reassuring in letting parents know that it is ok if a baby is a non-crawler.

What parents can do: They can keep a close eye on their baby's mobility, and encourage movement with simple exercises. They should contact the pediatrician if they notice that their little one is not crawling or attempting to pull themselves up when they are almost a year old.

11 Baby Is Not Given A Chance To Try

via Wallpaperflare

In some cases, parents simply don't give their babies the chance to try to crawl, or the opportunity to improve muscle movement and strength. While it is perfectly fine for moms and dads to hold their babies, there are some negative things that can happen if they are doing that all the time.

In addition, parents are not the only ones who love holding babies. Grandparents and older siblings are often guilty of doing this as well, and the truth is that babies need to have some time when they are not in a person's arms. That is because when they have a little bit of freedom, they can develop the strength that they will need to begin crawling, as well as walking.

It is extremely important that babies are able to explore their surroundings (with supervision, of course). According to healthline.com, it is good for babies to spend some time on the floor if they have not yet mastered the art of crawling. For some parents, this might mean that they need to hold their babies a little bit less, and put them on the floor.

Furthermore, it is a good idea for moms and dads to try to make sure that the area in which their baby spends time on the floor is comfortable enough for them. They should also place some of the child's toys nearby, so they'll try to crawl to them.

What parents can do: In addition to making sure kids get some time out of a person's arms, they can also reduce the time their child spends in walkers. The same goes for bouncers, as well as any other seat that will keep the baby confined to one spot.

10 Baby's Personality

Everyone has different personalities, and that is even true when it comes to babies. While some people are very active, and they are in a hurry to do things, others are a bit more laidback, and the truth is that even some infants can be like that is well. When parents are wondering why their little one is not crawling, they should take their personality into consideration.

That is because children who are a bit more laidback than others will likely not be in such a rush to reach certain milestones, according to todaysparent.com. But their parents should relax instead of worrying about it. Kids like this will eventually start crawling.

What parents can do: They can not change a baby's character, but they can encourage their baby to move by ensuring a safe environment and stimulating activities like, listening to music, as well as with play dates with older babies. They may also mimic crawling moves for their little ones.

9 Baby's Weight

Being at a healthy weight is something that everyone should strive for. However, this is something that is particularly important for babies. Being at the right weight is something that they need to do in order to reach certain physical milestones, and that is also something that can affect when they begin to crawl, or even if they start to do so at all.

Slightly overweight babies are usually very cute, but what their parents are not thinking of is the fact that their weight can be very harmful to them. Babies that are overweight might have more trouble doing certain things, like crawling, than others do.

According to reuters.com, a doctoral student in nutrition epidemiology at the University of North Carolina at Chapel Hill, along with some of her colleagues, studied this type of thing, and they came to an interesting conclusion.

  • Meghan Slining and her team evaluated 215 babies on several occasions up to 18 months old, and of the 152 infants found to be overweight, 20% (31) had delayed motor skills.
  • The team also found that 75 babies with high average measures of the belly, upper-arm, and upper-back skin fat, 23 percent (17 infants) had delayed motor skills.
  • In conclusion: motor skill delays such as an inability to sit steadily for 30 seconds were about twice as likely in overweight infants than in those who had a normal amount of weight and fat on their bodies.

It seems logical that babies who weigh more have increased difficulty in mobility as they have more weight to move around and lift off the ground.

What parents can do: Encourage a baby's movements by playing with them and placing their favorite toys and objects at a reasonable distance from him to move towards.

8 Baby's Clothes Are Uncomfortable

via Needpix.com

It stands to reason that if a baby is wearing uncomfortable clothes, his or her mobility will be reduced. Whether this may be a onesie that is too tight or socks that are too loose, the baby will be discouraged from crawling or walking if he does not feel at ease and confident about his movements.

One impediment parents rarely think of that might limit the baby's progress in mobility is the diaper. Why would they? It makes things so much easier, right? Well, according to ncbi.nlm.nih.gov, diapers introduce bulk between the legs, potentially exacerbating infants’ poor balance and wide stance.

There is evidence that suggests that there is a link between the diapers that infants wear, as well as their ability to crawl and walk. It is possible that diapers might be disruptive to little ones who are still trying to learn how to walk.

Since crawling is also something that requires a lot of use of the legs, it's also possible that crawling could be affected by the diapers a baby wears. This is something parents might want to keep in mind if their child has not started crawling yet.

What parents can do: Moms and dads can make sure their baby is wearing comfortable clothes he can move in with ease. These clothes should also allow him to grip with his toes. They can also allow the baby crawl naked for a few minutes a day to encourage increased mobility.

7 Baby Moves In Other Ways

via Air Force Medical Service

It is perfectly natural for moms and dads to begin worrying if their child is getting to the stage during which they believe that he or she should begin crawling, and yet they have not seen any evidence that their little one is ready to crawl yet. However, this is not always something that they should be particularly concerned about since that does not necessarily mean something bad is going on.

According to parents.com, there are some babies out there who just might not crawl at all, and that does not mean something is wrong with them. Just like adults, each baby is unique.

There are some children out there who are perfectly happy with finding other ways for themselves to move about on the floor. For example, if a little one does not crawl, they might do something like use their bottom to scoot across the floor.

There are also other ways in which they can show signs that they are becoming mobile as well. While it is understandable for moms and dads to worry about things like this, they really do not need to worry, especially if their little one is meeting all of the other milestones that little ones are supposed to meet.

Some of those milestones include the baby pulling themselves up, as well as learning what they can do with their hands. If a child is doing all of that, he or she should be fine.

What parents can do: If they notice their baby is not mobile at all, they may want to stimulate movements with simple exercises like stretching out the legs, support him sitting up, or placing the palms of their hands behind the baby's feet when he is on all fours.

6 Baby Was Born Prematurely

via Needpix.com

Being born prematurely can affect many different things. For those who do not know, a baby who is born before the 37th week of gestation is typically considered to be a premature baby, since most pregnancies tend to last approximately 40 weeks.

This is something that parents must keep in mind when they are trying to figure out when their little one should be reaching certain milestones since a premature baby should not be expected to reach those milestones during the same point in their lives that a baby who was born at the end of a 40-week pregnancy would.

One must take a child's adjusted age into consideration when they are thinking about when the child should be crawling. That is because premature babies who are 4 months old are not likely to be doing the same things that a non-premature 4-month-old baby is doing, according to webmd.com.

This just means that babies who are born a bit early are very likely to need a little bit of extra time to begin doing certain things, and crawling might be one of them. Being born prematurely can certainly have an impact on when a baby starts to crawl, but this is not something parents should worry about since they do usually catch up to their peers.

What parents can do: Follow all suggestions for children born to term, but do not force the baby to crawl if he is not physically ready to move, nor compare him to babies born at full-term.

Here Are 5 Reasons That May Be Cause For Concern If A Baby Is Not Crawling:

5 Baby's Legs Are Stiff (Hypertonicity)

via healthcare-online.org

Hypertonicity can severely hinder a child from movement. Also known as Stiff Baby Syndrome (SBS), hypertonia, or hyperexplexia, it occurs when muscles are extremely tight, according to katherinerosman.com. It is a serious matter because it is not only a physical problem but a nerve and brain issue as well.

Some babies who are born with Stiff Baby Syndrome are unable to stretch their legs out, or even put their arms over their heads. The only time their bodies are able to relax is when they are sleeping. In more extreme cases of SBS, it also becomes difficult for a baby to swallow.

Parents may also realize their infant holds his hands in fists or is unable to relax his legs. Likewise, he may have difficulty releasing an object and moving from one position to another. Babies with SBS may also cross their legs when they are being picked up.

The good news is that at this very young age, babies have the capability of re-routing their brains if therapy starts immediately after they get a diagnosis. Take note, however, that not all babies with stiff legs may be affected by SBS, and sometimes daily massages at home may be enough to release tension in the legs.

What parents can do: The first thing a parent should do if they suspect their baby to be affected by SBS is call the pediatrician. The doctor will most likely refer the baby to a physical therapist who will work with the baby and the parents. Therapy may last for the duration of the child’s development.

4 Baby's Legs Are Not Toned Or Are Weak

While there are some babies that are hypertonic, there are also others that are the complete opposite of that. While hypertonic babies are very rigid, hypotonic infants have poor muscle tone.

According to healthline.com, this condition is sometimes also referred to as "floppy muscle syndrome." This is something that is typically very obvious at birth.

This is not something that is hard to recognize since this condition affects a child's muscle strength, as well as their brain. It can also have an impact on their motor nerves as well.

One thing parents should definitely know about this condition is that it can affect children of any age. Some of the signs that usually present themselves in a child with this condition include a delay in crawling (as well as other milestones), in addition to poor head control and poor reflexes.

What parents can do: If they see that their baby is having some trouble when he is placed on his tummy and is unable to come into a tabletop position, they can initiate simple muscle strengthening exercises for him to do at home. If they suspect the issue is much more serious, or if the child does not progress in his movements, then they should contact the pediatrician, who will then refer them to a specialist.

3 It Could Be A Hip Problem

Babies want to start exploring their surroundings shortly after they leave their mother's womb, but their bodies usually will not allow that to happen until their muscles and joints are ready for it. This is why most babies tend to crawl or scoot around on the floor before they begin to walk.

By the time a child reaches the age of 9 or 10 months old, they should be crawling. However, there are some things that can affect when a child starts doing this, such as issues with their hips.

According to dynamicchiropractic.com, a delay in crawling can be a sign of a serious problem. It could mean that the child has congenital hip dislocation.

But on the other hand, this could point to some other serious conditions as well. While a delay is crawling is not always something parents need to be concerned about, it is something they should speak with their pediatrician about since it could be a sign of a serious underlying condition.

2 It Could Be Cerebral Palsy

If parents notice that their child has not started crawling after a while, they should take the child to his or her pediatrician. While this is not always something that moms and dads should worry about, it can also be a sign that the little one has some kind of developmental disorder, such as cerebral palsy.

According to cerebralpalsyguide.com, this can actually cause children to have a delay in many things, not just crawling. If they do not kick, or they have issues moving their eyes, that could be a sign that they have cerebral palsy. Other indicators of this condition are a failure to smile after they have reached three months of age, as well as a delay in walking.

What parents can do: Moms and dads who believe that their child might have a developmental motor disorder should speak to their pediatrician as soon as they can. They should seek out one that is compassionate, as well as one that has plenty of experience in treating motor disorders.

1 Baby Is Late In Other Milestones

via hatfielddcchgroup.org.uk

If a child is not crawling, but they are reaching other milestones, then they are probably fine. In cases like that, parents usually do not have much to worry about.

But this can be a bit more serious if the child in question is also experiencing a delay with those other milestones. According to parenting.firstcry.com, a delay in certain milestones can keep kids from starting to crawl. That is especially true for the ones that are supposed to develop the muscles a child has in their neck.

What parents do: Parents can watch their child to see if they reach any other important milestones. If they suspect their baby is not reaching other important developmental milestones, they should make an appointment with the pediatrician.
