Babies can sleep on their stomachs once they can roll back over to their back or sides themselves.
However if your baby is under 6 months it's best to try to keep them on their backs even if they roll over to reduce the risk of SIDS.
It isn't safe to put babies to sleep on their stomachs because this position increases the risk of SIDS.
The same goes for placing your baby to sleep on his or her side.
From the side-sleeping position, your little one can easily roll onto his stomach and end up in this unsafe sleeping position.
Always place your baby on his or her back to sleep, not on the stomach or side.
The rate of SIDS has gone way down since the AAP introduced this recommendation in 1992.
Once babies consistently roll over from front to back and back to front, it's fine for them to remain in the sleep position they choose.
Once a baby is 1 year old or older then it becomes more safe for the baby to sleep on their stomach.
