Three little stacking and sorting toys make this Pyramidou Wooden Stacking Game ideal for toddlers. They will find out which shapes fit onto the base. Then Build up the animals until eventually finishing with the heads to top the stacks off. I love these little stacking toys, just enough for a little one to manage and therefore feel a sense of achievement. Helps with hand to eye co ordination and dexterity. Each stack measures around 9 cm when complete.
