I have two boys both with ASD. Both of my children are gifted academically .My five year old is mainstreamed and our biggest challenge right now is RECESS. LOL!! That is what his teacher wrote on his last progress report. Social Participation, LANGUAGE ( a big one), self regulating, and body awareness are all at the top of the challenge list.
For my 3 and half year old ... Social Participation, body awareness , and motor planning are very challenging.
Its communication for us. My 4 yr. old daughter has found her words, she has hundreds now, and even knows what they mean. She's good with picture cards, and can say what each picture represents. I have even found her reading some things. Putting words into a sentence and having a conversation is not there yet. We are getting there! I have had yes and no answers lately, so that's the start of back and forth communication anyways!
