Show the toys

After a week later, I show the toy of two main characters to them because I want to make sure if they really understand the whole story and remember it. Also, I want to see what kinds of things can children imagining.

I can get some new inspire from it. 

I ask children to draw some character  in my book, 4 years old one and 6 years old one really  like do this, but 7year old one said that I don't know how to draw Milmil and becoming sad. I wondering to do some research  on this .
