Do a search for a sids hotline and you should find a good contact number she can call.
Life never is the same again. Intervals become longer and triggers less but the pain still comes when you least expect it. It's the hardest thing I have ever lived through. My baby died in 91 and I broke down over something and cried today. She does need someone to talk to.
The important things is that she is allowed to acknowledge her child and to go through the feelings. Fear, anger, the emotions can become intense.
Counseling with a GOOD therapist wouldn't hurt.
