There are some books that grow with your child.
"The game of sculpture" by Harvey Tullet is on our favorite books list since Mr Frog was 2 years old.
The book with no words but with endless possibilities. It gives child a chance to practice the creativeness, imagination, operate and experiment in 3d space.
I've noticed how the way Mr Frog works with the book changed in the course of time. First he used only elements available within the book. And he had no patience to build it at all by the way :) Now he incorporates many elements into his sculpture - toys, bricks, crayons, everyday objects - whatever fits into his project. He uses it in his imaginative play - builds a castle for the king or special trap for monster. And he turns into artist spending a lot of time creating his very special and unique piece of art :)
