Around how much did your baby weigh around 25 weeks ish ?? I'm pretty sure my son is weighing really small but the ultra sound tech didn't sound concerned guess I'll wait for my next apt on the 29th I feel so bad bc I had stomach surgery only a few months before I got pregnant and I'm trying to eat as much as I can for him . I just have a lot of restrictions :/ I get to eat anything just a small amount at a time .
