We just got that book. DS actually likes it and has tried to apply the lessons--to me! LOL.
It may be a bit advanced depending on what you want to teach. For example, it does teach greetings, but only offers looking at people as a hint, not the main point of any of the stories.
I just went and flipped through it and did not see anything specifically on not pushing. There are stories on taking turns, compromising, keeping calm and so on.
Also, the book itself is not super well put together. We've only had ours for a couple of weeks and the pages are already falling apart. I think it is meant for the adult to photocopy or use just as a starting point so it's not really meant for kids to handle. (And DS has not been rough with it, the pages just aren't bound very well.)
We do like it--not trying to discourage anyone from getting it. Please let me know if you have any specific questions about it.
And I'd love to hear if anyone has video suggestions! I've seen Bounce suggested here, but I haven't been able to find it anywhere to buy and it comes on while DS is at school in a Musical Mornings 3 hour block so it is inconvient to DVR it. . . . .
