I bought this set as a gift for my daughter's second birthday. She was very excited to receive this as she's Mickey Mouse's biggest fan. She has fun counting and stacking the numbered blocks and labeling the colors and parts. And she totes Mickey and Minnie around the house with her. She usually plays with this set as shown on the box - she hasn't mixed them with other Duplo sets yet. The train cars do not stay hitched to one another very well and this is the reason for only giving this set four stars. And Minnie usually falls over for some reason when she's driving the train through the house.
