He doesn’t have a diagnosis yet, but I’m pretty certain he does have ASD or old style Aspergers.
He gets so focused on numbers that you can’t interact with him.
His speech and understanding are fine in general.
But he gets so focused on counting (today it was to 5000 before school!) and doubling numbers/doing any kind of maths, you can’t seem to distract him or change course.
One of the teachers in his class noted that he finds it tricky to communicate with other children when he’s so focused on counting/numbers, even if they want to interact with him. It’s like he has tunnel vision.
Other times he’ll play quite happily with friends and run around with them, join in with their games.
He counts / focuses on numbers from the very moment he wakes up in the morning until bedtime. He absolutely adores numberblocks and wants to watch it all the time. He’ll draw each character too and colour them in.
Sometimes you can get him onto another subject for a short time, but then he’ll go straight back into it again. Other times, there’s just no distracting him.
