After my post on Friday, I took the time to write a book called "I Can Share" for Oliver. I use the term "book" loosely, as this is about ten sentences of content and some sketches that look like they were drawn by a serial killer. The whole thing uses 5 staples, 5 pieces of paper, and a black marker and takes about 15 minutes.
The story outlines a scenario where a boy yanks a red truck from a girl and yells "mine!". Then the auther explains that this is not okay. The girl cries so the boy can tell that he's upset the girl. Next time the boy asks, "Can I see that next?" and the girl eventually hands over the toy. The boys is now doing sharing. We walk through 2 more examples of the "Can I see that next?" scenario resulting in successful sharing and the book ends.
We then did some practicing around the house finding things that we could take turns using. At first it didn't work and we heard "Mine!" a bunch. But we did get some success eventually. Oliver read the book about 12 times over the weekend. He always loves the home made books.
We read the book in the car on the way to a play date and he proactively said the "Can I try that next" several times during the ride there. The play date went off well, and it was great for me to see that Oliver really does want to understand.
