By letting your two year old play with such gadgets you are retarding her mental development. GOOD JOB.
Disagree. There is a folder just for her with educational games and apps installed. She has learned some letters, numbers, colors, animals, vehicles, sounds, scenery, matching, etc... She isn't sitting there playing mindless games for hours on end.
Have you taken a look at the vast variety of educational software available on tablets? There is so much out there. My daughter is pretty advanced for her age (she will be two in mid December), but she can do so many things and has been completely potty trained for a couple of months now (I won't go as far as attributing that milestone to a tablet of course, I will take complete credit for that myself. (Well, and maybe my wife and daughter deserve a little as well.))
