Finally. After a whole lot of (ridiculous) tugging, pulling, pushing, and threatening, Child Protective Services took the baby into custody. The baby's mom went (voluntarily) to the psych hospital. Now at least I know that she'll have to do a lot of work to get the baby back. This is a huge relief.
I found out yesterday that I was not the only one at work who was really struggling. There were lots of tears behind closed doors, which doesn't happen much, believe it or not. And so. I only wish I had more time with him.
