Sids and suffocation

I'm seeing a lot of confusion on this topic lately. People seem to think that when a baby dies of suffocation which is truly a tragedy, that it is considered SIDS. But that's not the case. SIDS stands for sudden infant death syndrome, which means there is no cause. There has been 50+ years of studies and no one really knows the cause which would make it unbearably painful when you have a perfectly healthy child and you have followed all the AAP recommendations and your child passes from an " unknown cause". Now usually suffocation happens when there is a stuffed animal or a blanket in the crib and the baby accidentally breathes in too much of their own carbon dioxide which is equally as heartbreaking, but something completely different from sids. I hope I've cleared this up for people who didn't know the difference or were confused between the two, I just want to end this with saying I'm so sorry for anyone who has lost a child under any circumstances, I can't imagine what you have went through or are going through and my thoughts and prayers are with you xo
