Don't worry. They learn quick. I started worrying my son would roll out from my bed after he learnt how to roll over. I asked my mother-in-law if he could do the multiple rolls and she said no. The day after, he rolled out from my bed and fell. I didn't even know how he did it because he was behind me.
Yes ar..and the nurse said exactly what you said and she is absolutely normal and that I shouldnt worry! she can roll one way now...sometimes needing my assistance still...I'm keeping myhopes up but I can see her improving bit by bit!thanks!!!
