My ds is 2y8m and I'm querying whether he has hyperlexia and whether there's anything I should be doing to support. Does it even need a diagnosis?
Since turning 2 he has been pretty obsessed with letters and has known all letter names and their corresponding phase 2 sounds. He can reorder the alphabet when out of sequence and can recite the whole alphabet backwards (I struggle!!).
He can hear initial sounds of words, eg will say "whale starts with letter w and that makes the sound w", "v is for vulture, the sound is vvvv". He will spell words out that he sees but as individual letter names for now. He can spell his name verbally and can read it written down.
Is this a sign of hyperlexia? I'm aware this can be a trait of autism. Hes good with numbers too in that he can read them and reorder them to 20, will read door numbers etc but its definitely letters that is making me google.
