when i had my first born child i was so anxious and fearful about every little thing with him. i swear i would watch him sleep just in case something would go wrong, at least i would be right there.
it is a pretty small percentage, but it would definitely be something to worry about.
i know, right, and i had this nurse tell me the first week he was alive, that babies have died of sudden infant death syndrome right in their parents arm! it was so scary
