This sounds familiar. My son was a disaster through most of preschool. He started at age 2 and a half just two mornings per week. He would sometimes hit and bite other kids and even teachers. He seemed defensive a lot of the time when other kids (mostly) would come near him. He wouldn't follow certain directions, etc. I had to come pick him up once or twice and he spent some time in the office. When we moved, he seemed even worse in another preschool. Finally, after spending some time observing him and talking to the teacher, his behavior (which was very different at home) made sense. He had sensory issues that I never noticed at home. Home was quiet and not chaotic and preschool wasn't. He showed signs of oversensitivity to sound, smell and unexpected touch. I had him tested by an OT which confirmed this and he did do some OT for a summer. She said that she often sees very bright children who are oversensitive to things. Fast forward a few years and he is doing very well in public school despite a hard beginning in K. Maturity has helped a lot. His preschool doesn't sound like a good fit for him. Do you need him to go to school over the summer for childcare purposes? If you don't, I would keep him at home this summer.
