My DS is 4 and started reception last week. The school have been doing half days, but he keeps telling me it's really loud in the class and that he doesn't want to go in. We had to really persuade him this morning. We have suspected ADHD for other reasons, but loud places / noises have really been affecting him, so we were always worried about him starting school. We're being really positive about it, and I've told him that if it's too much / too loud, to ask one of the teachers if he can go outside for a bit. We haven't told the school we suspect ADHD, but I will talk to them about it before he starts full days. What else can I tell him when he's worried about the noise? Will he get used to it if he has sensory needs? Or will it get worse? I'm worried if he gets overwhelmed, he will lash out (which is what he does with us). Any advice or guidance is welcomed, thanks!
