content: We first learned about this toy when our baby was in the hospital. We attached it to his crib and he loved it. He loved it so much that we went and got one for him. Whenever he is upset we just have to turn it on and he calms right down. It has different settings so they either have something to see, listen to or both. It is really great for a young baby.I do not think that any nursery should be without this toy.
