At what age did you "let" your baby sleep on their tummy?

Good idea JustMe. I'll search for the guidelines and show DH

I guess we've been pretty lucky that even though DS has been mobile for ages, he's never really rolled in his cot til now. He's obviously just realised that he likes to sleep on his tummy. Gawd, imagine my DH if DS was doing this ages ago lol.

Marta has been sleeping on her tummy from the moment she could roll over.
