Insert you ipod, hang it on the crib and off you go.

The iCrib features two speakers, a volume limiter and a night light to sooth your little one. There is also a timer that allows you to play 15, 30 and 60 minutes of music before it turns off so you don't bored them with 5 days of classic lullabies or Mozart (delete as appropriate).

Available from in the US, the iCrib should set you back around $30. - learn about it / talk about it / deal with it At parents can find all the advice they will need to keep their children safe online.
