Hi,
There are some sensory behavioural issues in your son, like spinning, staring at the things close by, and lack of pointing could be a concern (although pointing can wait until 18m so you have 2 more months).
Instead of just waiting to see what happens, why don’t you do some exercises with him?
For example, for pointing, if you ask him “where is tiger?” and hold a picture of the tiger, does he point to it and how? Or does he not point at all? Tell me where he is and I’ll tell you what exercises our therapist recommmedd as we started from no pointing at all.
Everything can be taught, including the eye contact, pointing, giving , sharing, joint attention, pretend play, etc. The difference between typical and autistic kids is that autistic kids don’t have need to look at our faces and body language so they learn much slower. The exercises can speed up their learning, force them to learn.
It’s too early for pretend play, and that comes as one of the last things.
Does he show you things, if you say “give me ball”, does he give you ball?
We did our work following our speech therapist advice and later added exercises from the book “An Early Start for Your Child with Autism” by Author: Sally J. Rogers, Geraldine Dawson and Laurie A. Vismara.
There are two books on the Denver therapy, but this one is meant for parents to do work at home and honestly, it’s brilliant. The other book is just pure theory. Lots of stuff from this book is what our speech therapist recommended, albeit he charged us the 140$ per 45 minutes .
You can try some other ABA therapy books, of course .
I advise you to investigate, buy one of the ABA therapy parents books, and start the exercises. Autistic kids can be thought everything , to point, to show, to pretend play, and sooner they are taught that. The more progress they make now, the better social skills later in life. Lots of medial studies proved that correlation.
Whether your son has autism or not, I don’t know. He has some behaviours but at this age it’s a coin toss on whether he turns out typical or not. Some autistic behaviours are found in typical children, but it’s all about the cluster of behaviours, not just one or two things. Even then, doctors often can’t assess until the age of 4 or 5, so why wait until then and miss an opportunity to work with him. Even if you do an hour work a day, that’s an advantage you are giving him for the later.
