I wanted to see if everyone could chime in on their little ones hitting the milestone for rolling over. I believe the AAP says this should occur between 4 and 7 months.

Our little one could lift her head really high when on her tummy from the beginning so she rolls/flops from belly to back since the first week she was home.

She is now (4 months) trying to roll from back to belly. She will get all the way over on her side but her arm gets stuck underneath her so she rolls back to her back. Any suggestions to help her besides pulling her arm out from under her?
