DS1 is 3.9 and has lots of 'quirks'. He goes to 2 nurseries and both say he is quiet and well behaved. Just starting to join in a little with peers as very happy playing alongside.
At home he has several sensory issues eg
Only eats plain dry food (but eats all food groups)
Won't try new foods and gets anxious ( we never push him, just offer foods)
Dislikes many textures eg won't walk on fluffy rug. Wouldn't touch fur on top of Xmas stocking despite his excitement.
Dislikes wooly jumpers saying they itch. Once on he does wear them.
Hates new clothes because they feel different.
Won't touch some messy play eg fake snow, shaving foam. Fine with dough and paint.
Very distressed at hair dressers saying it tickles. Really struggle to get it cut.
Cries at swimming pool after swimming g because the floor is wet and slippery.
He is obsessed with counting and numbers. As a reception teacher I know he is advanced in this area. He is constantly asking and making up number problems, reads 3 digit numbers and makes his own links eg
Worked out 8+8=16 so knew that 80+80 must be 160.
At Xmas tree show he was just interested in finding all the numbers on the labels.
Reads prices in shops and compares amounts.
He loves games and puzzles which are very structured and safe. His imaginary play is at a very basic level (the odd time I can get him playing those sorts of games).
As his nurseries don't see any of this they have no concerns. Am I over thinking all this?
