Quoting khigh:" I would do it if you can watch him. Heck, when we were babies (in the '80's), sleeping on the stomach ... [snip!] ... so she would sleep on her side. Now, it's back only. I'm sure in a few years, the recomendation is going to change again."
Yeah, I was born in 88 and my brother in 82 and we slept on our stomachs so its my mom who is telling me to put him on his stomach. The thing is I read online that most infants who die from SIDS now are infants who typically sleep on their backs and a different caregiver puts them on their stomach. I can keep a close eye on him but there will be times that I am in the kitchen or dining room and he will be in the living room in his pack n play.
