I've learned to let go of some of my anal housekeeping behaviors over the years. I used to vacuum behind people when the came in my home
. I wouldn't worry about it. Sheets off beds is a sign of a clean home...not a messy one, lol.
Kids make messes and they know that. Of course, I do the same thing as you on this. I want my home to be perfect when they get here and I worry when it's not, lol.
