Too much Dora?

We never turn the TV on just to see what's on, but I do TIVO Dora the Explorer and Go Diego Go. These are 2 shows Emma really enjoys (not to mention shows that I can bear to watch!). I'm thinking she might be watching them a little too much though. These days, when we leave the house, Emma starts singing "Where are we going" with the corresponding answer "To the grocery store, "To Rebecca's house", etc... just like in Dora. And then, when we get back home, she starts singing "We did it, we did it..."!!lol But then again, I could say that it's educational TV since we were at Toys R Us the other day and there was a Diego display with animals from the various episodes and Emma went through them, naming them one by one, everything from a red eyed tree frog to a sloth to a pygmy marmoset!!lol May I add that I had never heard of these specific animals til I learned about them watching Go Diego Go with my 2 year old!lol And I'm embarrassed to say that I thought the pygmy marmoset was a sloth...Emma corrected me!lol At least she's not rolling her eyes at me yet!lol
