This is my great-grandsons favorite app. He is only 2&1/2, whenever he comes to visit he ask for Twinkle , Twinkle. Its amazing looking o dr at him doing the sign language to the song. His mother is deaf, when he goes home he loves to surprise her with what he has learned from this app. Thanks you soooo much for supplying this great learning tool.
