LO is 9 mo and we've been bed sharing on and off since he was born. He really prefers to sleep on his tummy which I don't worry about at all in the crib, but all of the sudden he's trying to sleep on his tummy in our bed and it makes me nervous. If you cosleep/co slept with your LO as they got older, at what age were you be comfortable with them sleeping on their tummy in bed?
Thanks!
