HFA is high functioning autism sure start is a centre that can offer someone to come and help for hour or so was offered to me
first dont turn his face to look at you and try not to shout easier said than done but my son reacted different if i wasnt shouting
thias is where it becomes battle of wills
get down to his level and calmly say what he has done wrong and try and get a reply such as ok so you know he has heard
tell him to stay in hall for example if unable to calm him dont argue but ignore walk away and leave to calm down then you can calm also
then go back out and praise for calming down or if been naughty explain why he was there and go and start again with no mention of naughty behaviour
try if you can to have some valuable one to one as acting out could be his way of grabbing your attention could you do playdoh or painting together and have fun
ask him what he'd like to do and see if this will help
sure start also offers days out my friend goes every monday look it up and see what is to offer i only know small bits as was offered help in my home
your not a shit mum his at an age that can be difficult you have new baby and not enough energy or time
but it is crucial that the attention he gets is positive and not negative as he'll thrive off any attention he gets
just cuddle on sofa read to him sing to him put bowl of water in lounge with water toys in , playdoh lots of talking and praise and try to have fun
make pizza together make anything together doesnt have to be lenghty in time but just that 5 mins positive attention and praise
even small thingsd good boy for sitting nice and eating , good boy that picture is lovely etc
also look up to see if you have a snap centre near by my ds loves going there and have all sorts of things they can offer you
