I think the baby powder floating around in the air isn't suppose to be good because the baby inhales and it gets into the lungs. This happens when you slam down the baby powder on just douse it on the baby.....just dont pour it straight on the baby's chest.
However, if you pour a small bit into your hand an rub it on your hands before you rub it on the baby then it reduce the amount that floats in the air.
If you put too much in the baby crotch area it mixes with the urine, vaseling, and or desitin and then it cakes up in the creases in the baby's legs. It's gross to clean up...I never put powder there. I'd use a little powder sometimes after the bath, but I didn't regularly use baby powder, just a little here and there.
As far as it being related to sids...i've never heard of it...my information is based on heresay 20 years ago when I had my first baby!
Lol, ok. Just lemme know what you find out =)
