Something that may only disturb a father of a daughter

So Mia has discovered how to pick her nose, although she really only sticks her finger in her nostril because she can. She also sticks her fingers in her mouth occasionally and her ear, because she can. So when I've been changing her recently, I noticed that she has also discovered another place to stick her finger. Yes, that's what I mean. I know it means absolutely nothing, and it's just her exploring because she can, but it's one of those things that jolts me out of my comfort zone and makes me realize that some day, far in the future, boys are going to be interested in her. And it makes me realize that I still haven't bought my shotgun.
