Pls let me know if this was not the right forum for this subject
My 3 year old likes the Toca Boca apps, Peek-a-boo barn and peek-a-boo wild, Bugs and Buttons, Dr. Suess Band, Doodle buddy is a free drawing one, there are almost all the classic Dr. Suess books on there, they are pretty good, it will read the story to you or not if you want to read it outloud yourself.
Montessori 100 board, Toca Boca, ZooWho, Read Me Stories, Miss Spider (stories), TinkerBell, and Phone4Kids.
ETA: Phone4Kids has no educational component whatsoever, but DD loves it.
I am also a lover of books , treehugger , and occasional soapbox stander!
