Versatile Mobile for growing Baby These are the key Developmental Wonders that this product can encourage in your baby: Language & CommunicationAs babies lie in their crib or bed, cooing at the mobile characters, smiling and practicing some baby talk, they hone their communication and language skills. CognitionThe mobile’s cute Into the Forest™ characters appear and disappear above baby’s head. This creates a sort of peek-a-boo game that helps baby grasp the idea of object permanence. As baby grows and begins to press the music box independently, your little one learns about the wonders of cause (pressing a button) and effect (music and lights). SensesThe smiling characters’ large eyes and the spiral's slow motion along with the relaxing classical tunes stimulate baby’s sense of sight and sound. EQThe soothing music, calming nightlight and steady movement create an atmosphere that calms babies and helps them go to sleep.
