DS2 (ASD) is nearly 4 and has started to become very controlling with his behaviour. He wants people to sit where he wants them to sit (by people I mean me and DH) and if DS1 or DD want to sit down he gets very upset about it. He keeps repeating 'Why', and he excalates until he is crying and inconsolable (he also bits himself and pulls his hair). He has a speech delay so its very difficult to explain to him what he wants isnt always acceptable. Shouuld we ride out the tears in the hope he will learn he cant always be in control? Has anyone had any similar experience?
