Nearly 5 year old has been in nursery and pre school since 9 months. Always played well and sociable has older sister of 7. Been in the nursery attached to his now school For year previous with no issues apart from some general bad listening stuff. Since starting reception he’s just become really violent at school. Two days in a row he spat, bit and punched two different kids and got sent to head teacher. This week he scratched a kid really badly across the face for not being let in at the sink. He got internally excluded as they call it at school today for a few hours...he’s 4! I’m mortified and confused. I’ve asked for a SEN discussion at school which I have appointment for on Monday which is great. What I’m seeking is anyone who’s experienced sudden behaviour change and what suggestions of paths to follow might be. My son seems really confused and unable to explain what’s going on. He seems to know he’s done wrong but can’t seem to control these outbursts at the time. His personality is mischievous but also he is very sensitive. I’ve often wondered if he has some kind of sensory processing issue. I’m so concerned about the ability to keep school supporting him given this number of early incidents and also him being seen as the troublesome child that parents tell their kids to keep away from. I want to support him as best as I can, help! Thanks in advance
