The Rocker Napper features gentle rocking movements and vibrations that can help soothe baby and develop body sensation and control. Parents can control the level of stimulation by activating or deactivating the product's various features. Reducing StimulationIf your baby seems uncomfortable or restless, try reducing the level of stimulation and examine baby's reaction. Let baby enjoy the hanging overhead toys without the music & lights feature or the vibrations and gradually try introducing the additional features. Increasing StimulationIf your baby seems uninterested or bored, increase the level of stimulation while monitoring baby's reaction. Rock the Rocker back and forth, add the vibrations and draw baby's attention to the dangling toys. Did you know Some babies love vibrations while others don't. When you first use this feature, monitor baby's reaction to establish which it is.
