This is why I make "baby quilts" 48x60. I never used blankets in bed with my kids nor did I use bumpers. my youngest still doesn't have a pillow in his bed, however he does have a blanket even thoguht he sleeps ON it not under it!
I agree with others that say if you have ever lost a child or a child that was close to you due to "crib death" you would think twice that they are "crazy" and "you lived through it" You might have lived through it but your friends brother or sister might not have. So I guess as long as its not one of "OUR" children then it doesn't matter!
Personally after losing a child if they said I had to sleep standing on my head while drinking water through my nose to keep my child from dying in the middle of the night while sleeping guess where I could be found! And no I am not a "crazy extremist".
