Butterfly Dreams 3-in-1 Projection Mobile "grows" with baby. It starts off as a motorized crib mobile with starry light show projection and 3 soothing audio modes. As baby gets older, convert it to a table top projection soother for extended use outside the crib. You can even use it as a linkable stroller mobile for on the go! Three soft butterfly bears on the motorized crib mobile help soothe, comfort and entertain baby. The bears gently float overhead as a soft-glow starry light show projects on the ceiling and walls, surrounding baby with soothing sights just right for developing visual skills. Three audio modes add up to 30 minutes of lullaby music, white noise or soothing nature sounds, too. Remote control is designed to hang on the nursery door knob, so you can quickly restart mobile motion, projection and audio without disturbing baby. When baby outgrows a crib mobile, Butterfly Dreams 3-in-1 Projection Mobile converts to a table top musical projection soother for older babies and toddlers, and a linkable stroller mobile. Clip the mobile to your stroller"s canopy to take it on the go! Requires 4 AA Batteries.
