I had a similar situation. I told everyone that I bet my baby would be small so if they wanted to get clothes for us then to get newborn sizes too. They all said she wouldn't fit them. They were so wrong. Nearly 3 months and she's just now starting to properly fit 0-3m clothes

The doctors can't actually tell how big the baby is my friend had to get a c-section cuz they told her her baby was going to be 9-10 pounds and was only 6 and it happen with my BF cousin he was only 7...mine came out 8 and we thought she was going to be tiny cuz me and my BF both came out 5

on the same boat, I didn't get nothing newborn. my baby was 5 pounds 10 oz.m nothing fits him either. lol
