DS is 4 months old and has just got the hang of rolling back-to-belly (he's been able to roll the other way for a while). Now he rolls onto his front in his cot to sleep.
I seem to remember that this is supposed to be OK -- so long as you put them down on their backs and they have the strength to hold up their own heads, then if they roll onto their fronts you don't need to roll them back again.
Can anyone advise on whether that's right or not?
