KIDEOS is a video site which collects tons of children friendly videos mostly from youtube, and categorizes them into several sections. You can choose a video by age, themes or characters. If it's children friendly, then ..., you're right! it must be Tadokist friendly, too!!
There are many characters and books popular among Tadokist, such as Dr. Seuss, Sesame Street, Kipper the dog and many more.
Wishing you a Happy New Year!
