My son is 3 and 5 months. We have a diagnosis of ASD and he starts special nursery in Sept. For the last couple of weeks his behaviour is slipping. When we r at home only. He climbs everywhere jumps on sofa. Squeals. Runs and throws himself on the floor. Hits me pushes me and his younger brother. Ignoring doesn't work neither does shouting. He asked for Cbeebies on TV then when that was put on he wants toy story. Help please my patience is slipping.
