Leo can turn book pages

Today I was reading a book for Leo. This is the second time I did this with him. He was looking at the book all the time and when we were in the last page, he put his little left hand between the pages and slowly push the page to the right. With a little help from me, little Leo managed to turn a book page for the first time! Then as if to prove that was not an coincidence, he "pushed" the another page from left to the right. And one by one, until he turned all the pages back. Wow, way to go Leo!
