Title says it all. LO is 6 months old (crikey! where did that time go?!) and just started rolling over this week. Although I'm delighted at how quickly he's progressed from struggling to roll over once to rolling over 3 times in succession, it leaves me a bit curious about sleeping. I put him to bed on his back but last night we were woken loads by him squealing because he'd rolled over and was squashed against the cot bars. I went to check on him during his nap a few minutes ago and he's lying on his tummy sound asleep. i flipped him over (soooooo carefully, his napping is rubbish!) and he's still asleep. What age do "they" say babies can snooze on their tummies?
