What an awful thing to have happen.
The accident did from what they've reported happen because of the mother's actions,but I think the loss of her newborn son is enough of a punsihment as it is.I can't imagine she'll ever get over what has happened.
The fact that she removed the baby and carried on driving whilst holding him and was driving on the wrong side of the road would immediately make me think that she wasn't of sound mind at the time.
She could of being suffereing from sleep deprevation or she could have had PND or she could have had a really traumatic delivery,pregnancy or both and could have been suffering from PTSD.
I don't think anyone will ever be able to judge that poor women as much as she'smost probably been judging herself since that awful day.
I hope she and her family are getting all the support and understanding that they need.
