Baby Clothes Size
My son is almost 5 months, and is mostly wearing 9 month clothing now because he's so long and big. He's 97th percentile for length and weight.
He easily fits into a lot of 12 month clothing also, but due to the stretch there are still a few 3-6 month old clothes he can wear still as well.
Logan was over 8lbs ag birth and he just went straight to 0-3months. By 2monthes he was in 3-6months. By 5monfhs he was in 6-9months. By 12 months he fit into 18month clothes. He now wears 4ts at almost 4 years old.
Vince wore newborn for a week. Then went to 0-3moths. He wore 3-6months by 3months. He now is 7months and he needs 12-18months in onzies, body suites, and shirts, but he needs to wear 9-12months in pants
