I don't think I mentioned that the Blessings, for the most part, do their own laundry. The day that is their laundry day is the day **they** do their laundry. Hence the oldest two doing the laundry of the youngest two. And when Kate and Grace get big enough, the boys will use that day to teach them how to do their laundry.
And my sons shall never say when they're in college, as my brother did repeatedly, "Mom, can you show me how again??" lol Not that my brother didn't remember how to do it! But I think our boys will be so used to doing laundry by then that the thought of asking wouldn't occur to them.
