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

[~mamaspice~]

I reckon one year old should be fine

I agree that 1 is definately fine PZ. DH is driving me nuts Lol.

Once a child can roll from front to back and back to front, then it is really quite pointless (imho) rolling them back. I believe, the major concerns with SIDS and tummy sleeping is baby not having the strength to turn their head.
Can I ask, how does you DH maintain the back sleeping during the night? Surely bub must roll over lots during the night.

5 months. She only does it for day sleeps. At night she sleeps on her back and does not move (her arms flail a bit, but she doesn't roll)
