Sad..

My SIL's neice had 9 month old boy/girl twins - I just found out that a few days ago their little boy died. They woke up one morning, and he had died in the night. They are doing an autopsy to find out whether it was from an illness or SIDS. This is so extremely sad to me. At what point in a child's life can you stop worrying about SIDS? I just can't imagine the horror of waking up one morning to find that your child is gone, just like that. You'd think you could get past a certain point and stop worrying about it. Life is so terribly fragile.
