Heaven's blessing

I just read my email and received an advertisement from Dayspring. I love the company and their products are encouraging. The advertisement was about a book for new mothers. The jist of the book was that the little life the new mom had was a gift from God and even though the mom doesn't have all the skills to be a mom--she will because she has this precious gift.
I've been deeply touched and disturbed for the past 2 weeks with the story of a two month old whose father put her in a hotel microwave and burned her. I've prayed for her because the first report wasn't too hopeful. As last week progressed, she improved. She is now out of the burn hospital and in foster care. The tv station managed to talk to mom and she says she's standing by her husband and wants the baby back.
Here's what I have a hard time understanding: My mother never experienced abuse to that extent but was certainly abused. She is approaching her 70's and is STILL dealing with the lack of love and nurturing she felt. She wasn't taken away from her family, CPS wasn't established or didn't get involved at that time. Why would a system built to "protect" the children give that child back? The mother has already stated she would continue to stay with her husband. A 2 month old baby isn't a big threat, doesn't even sit, crawl or stand. They pretty much sleep, eat and need to be cleaned.
