Hi
Am wondering if DS (4) may have some hyperlexia aspects. He is obsessed with numbers and letters and sounds out things as part of his conversation (eg: Y-e-s- Yes m-u-m mum:) ). He is also reading fairly well, maybe ORT yellow. He loves nursery rhymes and knows hundreds. He is also a bit inflexible with them and other things at pre-school and there have been issues with his behaviour which leads me to suggest he may have ASD (his sister is also being assessed).
I guess I am wondering if this is just an ASD obsession or something else, and if hyperlexia what I should be doing at this stage?
