My 3 year old daughter got these as a gift when she was born. She loves them. As an infant she chewed on them. As she got older, she loved looking at the letters and pictures. Now she loves stacking and building with the block books. They are of great quality and have withstood a lot of abuse. They are so great, that I just purchased them for my 3 month old niece. They are definitely a toy that grows with the child.
