KidSafe Keys introduces babies and toddlers to the world of reading! KidSafe Keys allows your child to bang away at the keys while learning letter names, shapes, numbers, and beginning phonics. No reading is required. Ages 6 months through 4 years. When your child presses a key, a colorful picture pops up, while a voice reads the letter name and the name of the animal or object beginning with that letter. Babies love the verbal and visual feedback as they press the keys. Toddlers begin to recognize and learn their letters and numbers.
