These all seem reall fun programs and I think our boy would love them. I'll look some of them up for him.
Still I am looking for some more interaction. What I mean with that is that questions are being asked and then the viewer (our kiddo) has to help finding the answer. Like in Umi Zoomie they might for example be looking for a triangle and then they show several shapes on the screen and say:"We need your help! Which of these shapes is a triangle?" Then they wait for a moment so that the viewer can point out what the triangle is or yell "The red one is a triangle!" and then Umi Zoomie says: "Yes, that's right. This is a triangle!".
Diego often asks the viewer to keep saying "swim, swim, swim" as to help an animal to swim faster. What I am looking for is that the kid has to take real action in order to help the cartoon figures on the screen. I find this in Dora, Diego, Umi Zoomi and Bubble Guppies very much, but where else do I find this?
