Not only are these blocks great in developing motor skills when stacking as building blocks, but very educational as well. As with all Melissa and Doug toys, these are quality blocks.
Whenever friends and family have children, I make their child's name in blocks and glue them together so that they can put them on a bureau or on the shelf on a wall. They really appreciate them.
My son is 6 mon , I have bought these block at 3 month and I dont use him to teach him the alaphat I teach him how to build the tower and knock it down ! He loves it. It teaches him his motor skill!
