Huh. Maybe I am expecting too much. I try to get both kids a bath twice a week. More if they are dirty.
I, for the life of me, could not figure out why my stepdaughter's mom seldom gives her a bath when she is there (she lives with us one week, then her mom the next with the odd extra day or two at our house). She arrived yesterday with greasy, matted hair again and told me that she didn't have a bath all week. But if her mom subscribes to the once-a-week theory, then that would explain it. She could just leave all of the baths up to our house.
