Dd1 (AS)- loves routine, likes to be in charge, wants to be friends but finds it hard to keep them, sensitive to sound, suffers with anxiety, want everyone to like her, gets upset easy, can't take a joke, very verbal (talks like an adult), top of her class at school (loves reading), a bit geeky (loves reading maps and learning about space and a very fussy eater.
Dd2 (HFA)- doesn't care about friendship, loves numbers, poor communication skills, speach delay, loves routine, hates noise, hates being around too many people (crouds), loves to climb, flaps her arms when excited and when running, loves being hugged (deep presure), not good at following instructions and doesn't sit still for long.
IO think the main difference is the language, dd1 was talking early, dd2 only started talking at the age of 3 and is still delayed at the age of almost 5.
