Game on.
I would do her chore and zone, and she would do what I normally do, along with enforcing house rules (as opposed to making up her own). As a bonus, she would demonstrate to the Hag who currently runs the household how a "Nice Mom" acts.
I promptly swept Mia's kitchen floor and threw in the mudroom floor for good measure. Next, I picked up and wiped her zone, the kids' bathroom. "Mama Mia, I did an extra good job on my zone for you :)" Then I was off to my bedroom for some one-on-one time with the computer. Ahhhhh. I visited and commented on blogs I hadn't seen in weeks and emailed a couple of contacts. My one-hour limit of screen time would be up soon enough, so I settled into a cuddlebag and watched some tv. I chatted with Hubs on the phone and then rocked out on my headphones and danced around the house.
Meanwhile... Mia looked after Elle and kept tabs on Cam and Cy all afternoon. The kids were all in on the switch, so when Cam needed his bottom wiped, and Cy needed a splinter pulled out of his palm, they knew who to call. She sent three kids to time-out for various offenses (which she enjoyed immensely). As occasion permitted, I showed her what I would have been doing, so she looked up the recipe I had in the works for dinner, did a couple of loads of laundry, wiped up marker from a doorjamb, re-swept up dirty footprints of four 9-year-olds running through the kitchen, wiped a spill on a shelf of the refrigerator, made a quick side-dish and rolls, and added cheese to the baking casserole. She figured it would be easier to just set the table herself rather than round up and prod the kids to do it, so she did. Elle was starving, so she got her situated in the highchair with her bib, a bowl of food and a sippy cup. After dinner, a diaper change, pajamas for Elle and Cam, checking and re-checking Getty's homework, rounding up the family for devotional, and getting the kids into bed.
What happened next was remarkable. Rob asked, "So, did you have fun, Mia?" She leaned her head on me and said quietly, "That was hard, Mom."
You should see the smile on my face.
