So, watching Doc McStuffins as a kid, I think what they didn't tell me about was that I'd have to get a blood test one day and that some kids have to do it at one point. (I've had my blood drawn multiple times, actually. I was never finger-pricked.) 

I stopped watching the show years ago, but did they ever make an episode tackling that, getting shots or just the common fear of needles in general? If not, why wouldn't they if they made an episode tackling cancer (or at least I've heard)?
