Thank you. Wonderful to hear how well D is doing now. My almost 4 year old son was recently diagnosed with a developmental delay, but I have my suspicions he might be autistic. He has some funny little quirks, is extremely attached to me, not in an annoying way, more he needs to know where I am a lot more than any of my other 4 children did at this age, and though he's always smiling at people if they come near him he will back off fast, some more than others. He's also highly intuitive, repeats sounds and actions, and rarely upset but when he is upset it's often something seemingly quite odd like facing a toy the wrong way or putting his cars out of order. Anyway, thank you so much for posting.
