The wife thinks our 4 year old is on the spectrum. He is strikingly intelligent, like perhaps a 6 or 7 year old, but when it comes to his emotions he struggles... Like perhaps a 2 year old.
School are investigating. He already gets some extra help - his teacher and his head called him a genius and the most clever child they have ever taught, respectively.
But he flies off the handle if he doesn't get his own way, hates changes in routine, is very sensitive to bright lights and loud sounds... I don't think he is neurotypical.
