Squealing whenever anyone comes near him. Any advice would be appreciated!

[jerikaka]

Is this typical in children with asd? He is fine with dh and myself, but ds2 and any other child comes anywhere near him and he squeals at the top of his voice. Very sensitive to noise as well, which is how I think his sensitivity to other children started. He is at nursery and copes quite well with good support, but at home he is driving me insane with his reaction to his brother. He used to squeal when his brother made a noise, but now he does it whenever I bring him into the room or ds2 just has to look at him sometimes and he squeals. Does anyone have any tips that might help? Anything would be appreciated!

A course I went on suggested keeping a log of this kind of behaviour - they called it ABC (Antecedent, Behaviour, Consequences - I think). So you note down what happens just before the behaviour, then describe the behaviour, then the consequences - so for example, what happens when DS1 squeals? Do you remove DS2, or say anything or do anything else? Once you've done this a few times you may be able to see a pattern - and then you can intervene to change it.

Others know more about it than me - I know jimjams does.

The other thing we used was a sound cd from BIBIC - it went from a very low to a very high frequency and we played it twice a day (lasts about 3 mins). We haven't done it for ages and DS2 has become much more sound sensitive - so maybe it works! With a very sound sensitive child you would need to have the volume down very low at first and then gradually increase it.
