My 3 1/2 year old son was diagnosed in May and I feel I am drowning in literature and nothing is sinking in. Bit of practical advice needed. How can I calm him down while he is having a tantrum. How do I deal with him when he is being 'naughty'. I totally list it and shouted at him the other day, felt bad straight away, I know I shouldn't but had got to the endoff my tether.
