I'm very disappointed with this product. I bought it when my daughter was 6 months old because it is recommended for 6+ months. However, she didn't start playing with it until 10 months. She likes putting the blocks inside the fish but gets mad when the 4th block doesn't fit. She also gets mad when she can't get the blocks out because she doesn't understand how to empty the fish by pushing down on his tail. Its overall fish design is what attracted me to the product however I am so disappointed with it.
