The new thing he likes is to sit under a folding table with a blanket over it, draped completely to the floor. I think it helps him block out all the distractions. He seems more at peace under the table than at almost any other time.
As different as they are individually, they are all the same in some of the symptoms.. Andy, my grandson is now 12, and has done that since he was 2.. It's one of the games we play, that all of the grandkids play together with me.. We build tents all over the living room, covering the entire room, with tipped over chairs, blankets (especially bought for this purpose) to create tunnels and small rooms.. etc.. It takes up hours, and he just loves it, and all of the other kids do to..
