Because I lost a child and I network every day with mothers who have lost children and I often do my best to heal their faith in God that has been damaged by clueless moralists.
And I feel a strong need to spread the word and tell the OP to butt out. Presuming he is a best friend.
Now, if you have selected clothes for your child to wear in his coffin and put a toy in his hands before they closed the lid, and then laid on the dirt over his grave the night of burial to keep the rain off....then we can talk some more.
Truth is immutable. What I posted is what I would advise as a best friend.
Knowing the pain that accompanies losing a child, when you've done everything you possibly could for that child, can you imagine the pain of knowing you had killed your child? I would want to save any parent from that unbearable pain. I would want to keep them from being taken advantage of during such a difficult time. Once it's done, there's no turning back.
