An MP3 player for babies might sound like a bad idea, but the SweetPea3 is pretty cool. It doesn't include headphones or a headphones jack, so baby won't burst his/her eardrums. It's also durable and easy for tiny hands to grasp. Only adults and perhaps a shrewd 3-year old can adjust the volume using a special button combination. You can create up to three playlists, and easily add new songs via USB (cable included!). All you have to do is drag and drop, no need for special software or any of that. It runs on one AA battery (also included) and can also run on AC power. The device has an auto-off feature that kicks in when it's running on batteries. The SweetPea3 comes in pink and blue, has 256MB amount of storage (expect a larger capacity model in the future) and sells for $89.95 at sweetpea3.com.
