ABA for Autism and ODD, can we do it ourselves?

[Chocolate4me]

Hi, my son is nearly 9 and recently diagnosed with Asd although he only seems to show a few signs, not wanting to be the first to say hello, need to be informed and in control, anxious, a bit slower to speak, a couple of sensory issues like hating collars and sock seams. But at school since age 7 he completely changed after being told off by a teacher for not coming inside. I feel he has taken on more of the role of ODD now and is quite defiant at school (a new school) will disengage, refuse to try work if he doesn't like it, cries excessively if he is told to do something he doesn't want to do. So after a lot of research I keep coming accross ABA therapy. Which is a bit confusing as it seems to just be promoting positive reinforcement which is what I tend to do, but perhaps there is more to it? And from what I've read it can cost like £40k a year??!!!
Does anyone know of any books/videos that I can use to try and help my son myself? We already have a timetable at school which lists him to just sit and listen to the lesson inputs and use a safe space, to earn a daily reward, but some days he can't even manage to do that! Normally triggered by another child saying he bumped into him and Ds getting anxious and then he won't go back into lesson etc.
I already offer him a daily reward of a bike ride or baking or something but it needs changing so regularly that I run out of ideas, so I'm wondering if this ABA therapy approach can offer anything extra but I'm not able to pay that sort of money!
Anyone used it and willing to shed some light? It's almost as if nobody gives much specifics about what you/they actually do

Hi

I'm an ABA consultant. Do you want to pm me a bit more detail about your sons needs and I can try and send you some appropriate resources/links and ideas that can help you.

Straight up I would see if your school offers any mindfulness clubs or any in your local area or there are books/apps you can also use. Mindfulness can really help with anxiety. Lego therapy can also help with the social side.

How are the school with managing his behaviour? Did he manage better in his old school? It sounds like it could be the transition that has been traumatic for him. I have worked with children in similar situations before. How long has he been there? They need to work on him feeling secure and safe in his new setting before they start demanding things of him. His anxiety will be stressing him out so any demand will be overload and setting him off.

Please feel free to pm me if you need any more help.

Thanks
