The On-The-Go box allows for me to close the lid and we can take it in the car as well. I put the box by her carseat so she can easily reach the books. We can discuss the books as we go from place to place, or she can read them to me.
The other box typically stays in the house, however it does occasionally venture into the backyard for some outdoor reading. These book are larger and aren't as easy to take on-the-go.
2. I have started a book just for my daughter. The pages are filled with family members, the alphabet, numbers, and words she is starting to use. I add to this book as her vocabulary grows. With each word I write short sentences or provide a picture. This allows for her to identify the people and pictures on the page, as well as, have exposure to the word.
