Query: Great books

These books are great. My daughter loves them. She spent hours on the ABC book and loves that she can do them over and over again when I wipe the slate clean. Repetition is key for learning and when you're having a good time with something don't you wanna do it over and over again?!Don't listen to those other reviews. The books have been great. If the pen dries up or gets used up, which it will if your child is using it, you can go buy another pen and keep using the book. It isn't rocket science.Have fun learning kids!
