The thing is I would NEVER tell someone else to go ahead and put their baby to sleep on their front.
BUT, at only 5 days old, and still in the hospital, the midwifes put DS down to sleep on his front, and he SLEPT.
Although he was a tiny wee scrap, he was a strong little bugger, and a fighter. He could lift and turn his head by 24 hours, and was only ever happy sleeping on his front.
I tried over and over and over, as did the midwives, to get him to sleep on his back, but he never slept longer than 20 mins n his back, even when I tried turning him after he was asleep.
As I say, I would never tell anyone else to do it, but in answer to the OPs original question. Yes I did ignore the warnings and go ahead, and yes I did feel that the fact that he could lift and turn his head made me feel better about it.
