There is a wonderful book called No, David that Asher just loves. A friend gave it to us just a couple of months ago and we have loved it so much already that almost every page is taped back together. Not from abuse, but from use. I think Asher can just relate on so many levels. He IS David. The book is very simple. It starts with "David's Mom always said..." and then every page has some variation of "No, David" with a great illustration. Asher and Naomi can both quote the entire book. When I am trying to snap Asher out of a funk I sometimes start saying "No, David!" instead of "No, Asher!". Asher says "No, Dabid." with a sweet little shake of his head. The book ends with David's Mom saying "I love you, David." And that is when I can relate to the book on the same level as Asher.
I've been trying for a couple of months to get Asher reading the book on video. I hope it's not against copyright law or something (if it is somebody tell me!). Turn up the sound so you can hear Asher's sweet words, too. I repeat what he says for translation.
