Omg I bought this app in mid March and 2 weeks later he MEMORIZED every single letter. I bought the entire set of everything smart (colors, numbers, etc) and he memorized it all. We’ll be walking and he’ll point out letters and say the correct one out loud this really helped with his verbal skills he talks so much now (still don’t understand him yet) but wow!!!!! Idc who says electronics aren’t good for kids. Mine learned the alphabet, numbers and colors in 2 WEEKS!
