Our 4 year old son is in reception class in a mainstream school. We are waiting on his draft EHCP with his main need currently being about Communication and Interaction. We aren’t on the neurodevelopmental pathway yet but that will be the next step. He struggles with transitions at school and adult led activities in the classroom which can lead to crying, screaming and falling to the floor which can stop quite quickly. However, since May half term he’s developed a habit when he’s told it’s tidy up time (despite warnings, visual prompts etc) or it’s time to do something else or not to do something, to take off his shoes and socks and his shorts and underpants. This can be in the classroom, outside in the reception play area, on the school field. On one occasion when a TA told him to remain in the classroom area as she was going to the office he took off his pants and shorts and walked to the boys toilets and was found there. He said he was cross with the TA. This seems to happen when he is cross/frustrated/upset. He doesn’t do this outside of school. The staff encourage him to put the clothes back on and sometimes it takes a while for him to comply. I’m at a loss what I can do about this as we talk to him about keeping his clothes on and he says sorry but does it again the next day. Not sure what can help redirect him away from doing this? Not sure if anyone has experienced anything like this in a school setting or has any advice?
