I have a DCB exactly like this. He is part time and when he is here it looks like a hurricane went through my playrooms. In less than 5 minutes he can destroy a playroom. I had to remove a lot of toys or put them up out of reach when he is here. All small toys in bins get put up and over the last couple months it's gotten a bit better. I find he has a short attention span with toys and too many options seem to cause him to jump form one thing to another and he is super rough with stuff. I find less choices help, and cleaning up everything he dumps.
