DS3 is 3.6, currently waiting for a multi-disciplinary assessment. I've noticed something that I'm sure there is a word for, but can't think what it is.
Reading a book, there is a picture of a jigsaw, he sees the overall picture but doesn't seem to grasp the jigsaw element. Same with a picture of a book, he recognises the pictures on the page but not that it's on a book. And this is a much loved and read book so have modelled back "yes it's a Jigsaw. A rabbit Jigsaw" countless times.
