We've had this block set for about 2 months. I bought one set for a cousin who was turning 2 and one set for my daughter who was 19 months. Two months later, she still likes to stack them and then knock them over. The colors and pictures are vibrant and cute. They nest together so they don't take up much room when they are not being used. I would recommend these for young children. They help develop hand-eye coordination. As a parent, you can talk about colors, numbers, letters, and animals while playing with this toy.
