Yes I asked her why and her response was he doesn't have anyone to play with at home so she wants to observe him playing here, how he reacts to other kids, how he responds if someone takes a toy from him, etc. There have been no behavior issues. I do communicate with her. She asks me a ton of questions at every pick up, how he ate, slept, played. It could be the thought of going back to work and leaving him here 5 days /week.
