DS started school in September and I’m really struggling to find him some properly fitting school trousers. He has ASD and his fine motor skills aren’t the best so they need to be pull up ( no buttons or zips). I’ve tried George, Next and some from the local school uniform shop but they all start falling down like hipsters. I’ve tried different sizes and even the ones that feel a bit tight on the way up have the same problem. He always wore joggers at nursery and we never had this happen. Has anyone else had the same problem and did you find a solution?
