For context, I'm an elementary school teacher and think I have a good handle on behaviour management as a whole.
My son is 5 and will be starting Kindergarten in the fall. He has always been very physical with other kids and people. He was the biter in the infant/toddler room, although that resolved itself finally and we've had no behaviour issues at daycare since. However, I do still find him to be very touchy with other kids. If he's standing in a line-up, he's bumping his body into those around him. If he's sitting in circle times, he's touching the kids around him. If his brother walks past him, he'll reach out and grab or hit him. We have been working with a private OT for the past year to address this and some fine/gross motor concerns, the latter of which has mostly resolved. Her thought is sensory seeking due to retained primitive reflexes and he uses people around him to find his place in space.
While this has been helpful, as a teacher, I know how exhausting, frustrating, and tiring these behaviours are. When we see them at home, he is removed from the situation and takes a break. I've talked to him many times about how people don't like that, friends want to feel safe and that hands on anyone else's bodies are not okay. His daycare teachers don't express concern about these behaviours and say he doesn't stand out. I do worry that this is partly because he's been there for so long so the other kids are maybe used to it or he is standing with friends that do the same things.
Either way, I'm getting incredibly anxious for Kindergarten and the social and academic implications that can come from this. I don't want him to be ostracized by his peers or become a behaviour issue. Overall, he is a really great kid, but I spend a lot of time worrying that this is going to be a barrier for teachers and classmates to want to get to know him and for him to succeed and thrive.
Any suggestions, experiences, ideas are welcome!
