Kalena likes to play a game where I chase her around the house asking, "Who's gonna get her bum spanked?" She laughs hysterically as I chase her, and while she runs she'll say stuff like, "Gehher!" (get her) or "panka bum!" (spank bum) while patting her bottom. We don't spank as punishment. (Pretty sure she wouldn't think this was such a fun game if we did.)
BUT. I'm just waiting for her to start saying, "panka bum!" and patting her bottom in the grocery store or somewhere. I'm sure that'll be fun.
