DS, now 6, went through a phase between the ages of about 10mos - 22 mos (when his sister was born) where he couldn't "play" with certain things. He would set them (any "figurines" he had)up on his little play table, like he was going to play with them, but they only sat there. He would go nuts if we changed them. This is about the time that I was concerned he may be on the spectrum. I agree with no5 - sounds like he's more flexible than DS6 was at that age!!! smile
