We had our 6 month well baby and well baby is growing like a weed. She was 4 lbs 5 oz at birth and is now 15 lbs 5 oz. But she wont roll over yet and pedi is starting to get concerned. When did your preemie roll over. My lo just started tolerating tummy time about a week and a half ago as of 12/27 she wasnt even pushing up on her arms and now she is doing that really well. I know she will get it but part of me is worried. Ughhh preemie worries suck!
