Not educational but Peppa ***'s Holiday is the absolute favourite followed by the CBeebies app
Edited to say - that wasn't rude - it just said 'Peppa Peee- eye- gee's' Holiday

DS also loves Art Maker and Playschool Playtime! Toca Boca has some good ones too, as do Sesame Street (Elmo loves ABCs and Elmo loves 123s) and Fisher Price.
Playschool playtime, mister maker, peppa *** holiday, monkey lunchbox, Lego duplo, and there's plenty of puzzle, coloring, alphabet, songs ones, just do a search.
