[Q]: My daughter loves her blocks. She will get them all out and look at each one until she finds her favorite. She likes to shake them and see what each one does. These are cute little blocks that have hours of imaginative playtime inside. They also have blunt corners, so no sharp edges like wood blocks for the safety of smaller children. The fact that they have the letters of the alphabet and a corresponding object inside makes them a great learning tool even for older tots. We have really enjoyed these and recommend them to our friends.
[A]: Positive


[Q]: The book covers several generations, so with each generation you have to re-learn all the characters. It is difficult to keep track of who's who when every time you get to know the cast, 200 years suddenly pass and we're in the middle of a new crisis. I didn't read the whole series because of this -- it was obnoxious.
[A]: Negative
