Quoting Alyssa's mommy [EBFT]:" I remember reading that it is highly unlikely for a family to lose a second child to SIDS, almost unheard of. I was trying to find an article because I thought it may help but can't find one yet. "
SIDS is a rare occurance that has no real reason or even a "repeat" gene so to speak.
OP~ Did the funeral home refer you to a grief counselor? If not, maybe you will want to find one. The loss of a child is something a mother should NEVER experience. I understand the desire to TTC right away as well. I am terribly sorry for your loss and wish you comfort in this time.
