I wondered how you handle the mopping issue. I vacuum and mop around everyone knowing that they won’t be there forever and I have enough to do otherwise to keep me busy until they move and, if not, I’ll just catch it the next day. (We’re not talking flexible here, we’re talking Silly Putty.)
I mop when it gets really, really bad! DP decided to do the tax return, not that that’s bad, so I put the kids in front of the television. It mostly worked, with some breaks for baby-nuture and Frank-clobber.
The only children at home are James, Vlad, Frank, and Kathleen. It’s like being an only twice as large as normal family!
