I hope the little girl and the mother can both come to peace with the horrible decision that the mother had to make.
What an awful decision.
However, I know that if I could only take one, my older daughter would be the first to tell me to take her little sister.
The mother will be in denial and then be finding ways to punish herself.
This is not going to be a good outcome for this family.
G-D HELP THEM.
