what is the average height and weight of a 4month old?
my son goes for his four month check up next week...
He was 8 lbs 4 oz 21inches at birth
14 lbs 8 oz 26 inches at 2 months
I am pretty sure he is somewhere around 18-19lbs, 27-28 inches now....I tried weighing myself then weighing both of us on our scale and there was 18lbs difference exactly. I tried to measure him as best I could because hes a wiggle worm and I got 27.5 inches



But I will know for sure next week

my son is really big. People always ask me if he is between 6-7 months old and I am like....no. lol It isn't very fun carrying his carseat lol but usually I just make daddy do it lol...unless I am alone that I usually either put him in the stroller or just carry him.

My son was a big boy at birth, he weighed 8 lbs 11oz and 21 1/2" long, he has two month check up at the end of this month but we estimating him to be close to 18lbs by then since he's about 16lbs or so now at most lol. Everyone keeps saying he looks like a four month old instead of two months and he's a chubby boy! lol

Wow, only one oz difference lol. Any idea on how much he might weigh right now or going to wait to find out? I'm just curious.

I have no idea. If I had to guess probably around 15lbs. He fits in size 2 diapers and 3-6m clothes comfortably.

Yeah, his size 2s are getting tight on him. We're hoping to finish out his size 2 pack before putting him into size 3s but we may not be lucky lol. He fits into clothes up to 6-9 months depending on how they are made, but he does fit into 6 months comfortably and those are mostly hand me downs from my sister in law too. Which I'm happy about lol

my LO was 8lb 7oz 21 1/2 in at birth. I go for his 4 month check up tmw(he turned 4 months last week). Im pretty sure hes 17.5lb and has to be atleast 27.5in. Hes in all 6-9month clothes and size 3 diapers. I feel like im looking at a 6 month old not a 4month old!!! it makes me sad that hes sooo big(atleast compared to what his sister was)

My son was 9 lbs 4.7 oz 21 inches at birth. And we did the same thing where I weighed my self and then both of us and there was about an 18 lbs difference. And last time we measured him he was about 25 inches. We will find out next week at his 4 month check up.
