[POSSIBLE SPAM] Re: Re: Autistic Brains - slower to react to sounds - new study

[Guest guest]

Its so funny, with my boy, I know to wait, - i ask him to shut the

door (to keep the heat in) and I wait watching him and about 4

seconds later, he goes to shut the door. same with taking his shoes

off in the house (canadian custom) - he runs in the house from

outside, straight into the living room, turns round back into the

hall and then takes them off and puts them away

yes, you are right, repeating would not be good - just waiting -

presuming that they will hear and understand - to repeat what has

been said to our kids is judging them that they have not heard when

in fact they have heard, they just need time.

my mistake
