Munchkin recently added the iCrib sound system to its line of baby products. The iCrib attaches to baby cribs and features a cradle with inserts to fit the iPod and other MP3 players. The system also has a built-in nightlight and volume limiter, sleep timer, adjustable straps to fit on crib rails, and three modes (music only, lights only or both music and lights). “The iCrib lets you choose the music that soothes your baby to sleep—because some kids are a little bit country, and others a little bit of rock ‘n roll,” says Munchkin. The iCrib sells for $30.
