Shelli, Sorry that I skip your message when reading the reply (I have to go for eye check..=_=), it is interesting to bring out about "schizophrenia", somehow we did feel like he has some hallucination. It is really hard to tell as at this age, kids have lots of imaginations. I will check it out, thanks a lot.

Hi Aufilia, thanks for sharing, it sounds like my son. He does do sth else at home (e.g. he likes to learn phonics, like to play balls, and like to listen to musics), but in a new environment, he only does his maths, i think he feel safe about it. He is a very anxious kid. Too bad to know that your DD dx with ASD in age 8 but not at age 5, my son has to do evaluation every years to check if he is in the spectrum of ASD or not. Somehow i really hope that if one day he does dx with ASD, please dx it as early as possible such that he can have free therapy as early as possible. =_=
