My ds is 5 weeks old and was actually born 2 weeks early (so really only 3 weeks) and tonight he rolled from on his tummy onto his back!?!
T can't really remeber from my dd who is now 2YO, but this is early to be doing this surely? He was born @ 38 weeks weighing 9lb 6oz so is a big baby but 5 weeks?? OMG! lol, he has really good head control too.
