My oldest has had a tough year. 3 can be hard as it is, but he also has had medical issues and a new brother. I switched jobs and started him at a place in September. She was very negative and basically made me feel like my son was a chore to watch. She also made me feel he was behind other kids (her words!) She meant well, and I was hoping it would work out, but I couldn't take it anymore. I just thought he was going through regular 3 year old testing boundary stuff. I switched, and my sweet boy is back. The current babysitter has nothing but great things to say about him. I hadn't realized how much the old place was affecting him.
