If you buy just one toy, make it a set of blocks. Endlessly useful, they form the backbone of any toy collection. In fact, if you only buy two toys, they should probably both be blocks.
There are so many different types of wooden blocks for children, from colorful or natural wood to perfectly square or irregular shapes. Whichever you choose, a good set of wooden blocks is one of the most essential toys for open-ended play. There simply isn't a more versatile or durable toy. With blocks your child has the scope to build, sort, carry, count, create and imagine. Blocks are the definition of open-ended play.
