### ⭐⭐⭐⭐⭐ LeapFrog is the best!
*by L***B on January 9, 2024*

My 3 and 5-year-old granddaughters love using their LeapFrog "computers". We have several books that the girls can interchange. However, when their uncle started talking to them about the stars and planets, I found it a little difficult to find something to continue to spark their curiosity of the universe. Then I found this. What a great addition to their collection.
