Guilt is punishment for herself

I was shocked by this news at first sight. I can not believe the tragic story which is made by a mother. Meanwhile i was angry with this stupid mother when i read beginning of this news, because she was so reckless that lead death of her baby. I am just wondering if she does not love her baby, why does she give birth to baby. But now i change my attitude to this poor mother. I know she is inadvertent and she must be very sad to this tragic story. What's more, i have watched this video show and it was really tough to watch. i saw how sad this mother was , even she wanted to die. Her pain and guilt are apparent, she said she coud not forgive herself.
As far as i am concerned, i do not think this woman should get jail. There are two reasons for my view. On the one hand, she made this badly result because of changed daily routine. If she does things as usual, she will not leave her lovely baby. On the other hand, i know she has another daughter who is just five years old according to this video show. If she gets jail, that girl will lose her mother and can not grow up happily. In addition, this poor mother has have lost one of her baby, how can she stand lost another one? It's unfair to this mother, after all she does not want to leave her baby. Now she is so guilt and she said she was a bad mother. I think she will live with guilt forever and this is serious punishment for herself. So please give her another life with her five years old daugter.
