Say hello to baby’s best gal pal. Sis is the same soft, cuddly friend that responds to baby’s touch with silly sayings and sing-along songs – but now she’s got Smart Stages technology that changes the learning content as baby grows. She’s here to make sure learning never ends, responding to baby’s touch with silly sayings and lively sing-along songs about body parts, feelings and more. Press the heart to see it light up and twinkle to the music. Because every baby develops at their own pace, Smart Stages technology gives you the ability to select the stage that’s best for your child. There are a variety of developmentally appropriate songs, phrases and sounds within three levels of play. Sis’ light-up heart even twinkles along to the music! For ages 6 to 36 months.
