Ergonomic hardware is fundamental for baby learning, where tablet computers and touchscreens are preferably used instead of keyboards and computer mice. Also, a sandbox environment is created, to disable the use of the keyboard (excepting some combination of keys that can only be typed by an adult), taskbar, and opening of other programs and screens. Child computer keyboards may use large and differently colored keys to help differentiate them. Baby and toddler computers include ABC keyboards. Some child computers include QWERTY keyboards as an early aid in learning typing. Small mice, about half the size of a typical adult mouse, or large trackballs are used in toddler's computers. They are programmed for “one-click” operation. The case may be reinforced to protect it from misadventure. Such computers are not seen as a replacement for time spent parenting.
