DS is 4 months old tomorrow and for the past 4 days has been rolling from back to tummy VERY confidently! He does it all the time when I put him on his back on the floor and now he's doing it in bed too. Right then I checked him in his sleep and he is on his side but I know he will end up on his tummy. He is still wrapped though does break out of them now too.

Should I be doing something to prevent him from rolling in his cot?
Should I stop wrapping him?

Anything else I should know?? Thanks!
