Building Block Kits are the perfect toy for a young child. These small sets of wooden blocks are great for children roughly 3 to 4. For such children larger sets are a waste of money as they won't employ more than 50 wooden blocks at a time. (They will learn the names of shapes however). We can't stress too much that the way to buy blocks is to start small and expand the set over three of four years, enlisting relatives, marking birthdays and holidays. A 3-4 year old needs to be encouraged to play with blocks by playing with them - and more than once.
