Hi! I have an 8 year old that was diagnosed at 1 1/2, all I can say is good for you for the EI! A great book is out of sync child! I just picked up a couple at a conference, have to get time to sit and read them! My son has a hard time with changes in routine, I do let him know ahead of time what we are doing, but life is not scripted , so I make him aware that things can change. He used to have a hard time playing by himself, he used to line up his toys till they were perfectly straight, which to him never were. The OT said he has to be made to play other ways. Now he can play make believe with his lego guys has a spectacular mind! Picture cards are great for routines, I jsut saw Temple Grandin and she suggested for kids with visual issues glasses with a pastel hue. Of course your child is very young so that might be diffulcult. AUditory I keep headphones in the car all the time. He has gotten better with like going to the show, but a parade or something he has to wear them! Touch, my son would't even allow you to hug him, though the brushing technique he over came that, but there are stil certain fabrics that he cannot tolerate. He is a sensory seeker and requires weight! HE uses a weighted blanket, likes to lift heavy things, very impulsive, that is the toughest thing now. He used to run away all the time, he doesn't now, the weighted things helped with that. I know once you get a routine and find ideas to help you out you will be ok. There will always be something, but you will learn a strategy to get your child back on track! CHeck out the facebook page for this group it is awesome they have tons of great ideas and resources!!! We are here for ya!!!!
