I’m a bit worried about my 16 month old son. He spends quite alot of his days laying down on the floor pushing his cars along. I’ve not seen another toddler do this before. I can distract him out of it to play with something else for a bit.. but his default is always back to laying down with his cars. He’s always enjoyed wheels and spinning things since he was little. He makes good eye contact, responds to his name, points, claps etc but isn’t really talking yet or saying any words, just babbling. He is a very cautious child and observed alot before getting involved, he doesn’t really enjoy playing on swings yet. At a playgroup he will only play with cars. I’ve googled the laying down thing and it suggests ASD. Has anyone had anything similar?
