Book is over 600 pages and the print is so small it was difficult for me to try to read so I returned it. Perhaps if it ever comes out on Kindle I would try again.

My little boy is just getting interested in these blocks. They are too cute! He's learning to manipulate the block in his hands. The little things inside the blocks are adorable. Some spin, some twirl, some rock. A definate upgrade from the standard wooden blocks.

Positive
