DD (3.3) is being referred to early support due to a lack of social interaction with her peers. She has always been 'different' so I am on board with this because if there is a problem obviously the sooner we find out what, the better. I hope.
HV suspect ASD. But I'm not really sure, because she has no issues with routines, she plays very creatively, and sometimes seems to be OVER sensitive to my emotions rather than unable to read them (so when I have told her off, an experience which has to be done gently because she withdraws and retreats if it's overdone, when my smile comes back she will say 'oh, Mummy's happy again!' in relief) (My apologies if my layman's knowledge has me misunderstanding ASD).
However, she does have some red flags in that she doesn't express things about herself (like hunger, fear, illness etc), has never really shared anything with us that wasn't in a book (although she is starting to do this now), and she still doesn't talk about herself using 'I' or 'me' (it's by name or 'you') even though every other pronoun is grammatically sound. And when she is pretending to be a toy she DOES use I.
She is very sensitive to stimulus. In busy environments she is fine for a short period but is quickly tired out by them and needs some time alone to recharge
Certainly nothing to this point has stood out as an obvious possible dx. She does seem very bright, she definitely has a phenomenal memory, spoke early and talks in long sentences with lots of detail. She walked into our bedroom after I put up a new mirror and said 'A magnificent mirror!' The clear pronunciation and long sentences make the dodgy pronouns stand out even more, however.
So... is there anything other than an ASD that anyone knows of that can cause these kind of very specific expressive oddities? I really appreciate your help; I'm new to this and a bit nervous, so please be nice :-)
