The Dreams-in-Sight Mobile not only will keep your baby intrigued, but helps develop her visual tracking skills with a unique rotating canopy. The canopy projects soft moons and stars directly above, while the light projection ball moves in the other direction for a truly compelling light show. Your baby will love the four nature friends and the soothing music selections, which include classical, lullaby, soothing spa and nature sounds. The unit has a remote control, allowing parents to activate the music and motion without disturbing their baby. And to save battery life, it automatically shuts off after ten minutes. When your baby gets older and begins to pull up in the crib (at around 5 months or so), the arm and canopy detach from the music box and the music box remains in the crib for Baby to enjoy. Its large, bright-colored buttons are easy for Baby to activate in the crib. Requires 3 "AAA" batteries (not included).
