We have had our baby in the big cot now for a few weeks but he’s just started rolling around fully onto his face when he is sleeping and I’m worried he will roll on his face whilst sleeping and suffocate, do I need to worry about this or will he simply roll back over if his face is down on the matress, I’ve turned him back on his side a few times but I just worry he will do it whilst I’m asleep. He can sit up fully now and move about well and is almost fully crawling.
