My 19 month old twins were just doagnosed with pdd-nos. They each get their own therapist for 2 hours each day. One of my guys , whos is ALWAYS happy and laughing, did terrible. Im assuming cause it was a stranger in here putting demands on him. She wasnt even that firm today, she said this week she is just gonna let them get to know her. He screamed and cried, and kicked his legs and arms and kept arching his back and laying on the ground.. I have seriously never seen him do this .... I hope this will pass quickly? Anyones child started like this, and then got better once they got more comfortable?
