Pretty Miss K-Cee, I need to tell you this. I was a middle kid, so was both the obnoxious kid sister at one point, and the one with the obnoxious kid sibling following me around at another. So I am in a position to give advice, okay?

Put up with "da kid" for a while, she'll eventually give up the following thing, I promise. She just wants to be able to do everything you do, and gets frustrated when she cannot yet, just because she's too little. All we kid sisters remember that.

Eventually she will figger out her own thing to do, and you guys can start to be buddies then, okay?

One of the funniest parts of being middle kid was bringing home a human pup one weekend when I was in college (I was a sort of nanny), and watching as it followed around my youngest sibling, and the rest of us just chuckled and said "grin and bear it kid, that's what you did to us!" I think even Dad was secretly chuckling that weekend!
