Is your one and a half year old in? Mines still in a 2. My others were 6 by now...
My almost 14 month old is in a 4.
my son turned 1 in January, and he has been in size 4's since then, but my daughter was petite and was in two's until at least 2.
Your one and a half yr old is still in a size 2? Holy crap...tiny kid!
My son turns 2 in August.He wears size 4
I want to say 4, maybe still 3's at that point.
My son was in 3's what felt like forever! He's 20 months now and just got into 4's right after he turned 18 months. I switched when he just hit the weight for all but 4's. He could have fit in them sooner but I waited a couple extra pounds before switching this time.
My sons 16 months and in size fives . He's a chunk !
My dd is 15.5 months old and can wear a size 2. She is in cloth diapers, but this past week was sick and was pooping non-stop so I got disposables for her and she still fits a size 2.She is 18lbs and 27 inches long.
my ds is 18 months and we use cloth, but he can fit into a 3 or 4. hes almost 26lbs/31".
i am betting your kid would fit in 3's better.
My daughter is very skinny with a big butt she will be two in Sep and in a size 5 I can't imagine a size 2....a 4 leaves lines on her butt and gives her diaper rash. But she is potty training and wearing 3t pull ups and she wears 2t clothes.she is tall
