content: I got this when my son was four months old and he is now 14 months old and still uses it to go sleep. He loves to "talk" to the fish and every night. He loves to push the buttons all the time to make it go. When he was younger the music on this was the only thing that calmed him down. It is very durable as my two year has unhook it and it fell on the floor and it still works fine. I would recommend this to everyone,the money is well worh it, and I know he will be using this for several more years as he loves this still.
