I have 5 dc, 4 of whom have sn. 7 year old (the one without sn) has asthma, glue ear and hypermobility. I've wondered for a while if there was maybe something not quite right with him. He really struggled with going into year 1. His handwriting is terrible and he writes really slowly (he is left handed which may be the cause of this. He talks constantly and seems to have no filter at all. He struggles to concentrate when he is doing his homework but he can play chess really well for his age and he loves playing board games. At the moment he is in 2nd place in the school chess competition for year 5 and under which is brilliant considering he is only in year 2.
Anyway my friend who is a teacher said she thought he might have adhd. I'm not sure, I would have thought he would be more fidgety if he had adhd. Tbh with 4 of my dc having sn i'm not sure what's normal anymore.
