This happened tonight.
As I was in my bathroom doing my makeup to be ready for date night, Luca kept coming into the bathroom and rubbing my pants with both hands. Then, she would leave the room and come back a couple minutes later to do the same thing. I thought she was pretending to wash my legs and as long as she was happily occupied, I was fine playing along. But then after awhile of this game, I thought "I wonder if she is putting something on her hands and rubbing it on my pants?"
I quietly followed her on her next trip back to her room. Diaper ointment. On my pants. Apparently my legs have diaper rash that needed her care.
Oh Luca, sigh.
