Are there areas of your house you don't let your kids go?
I'm having trouble aligning with my husband on household boundaries with our toddlers. We have no attic. We have an autistic teen whose room is on the top floor. His room is very spacious and stores Xmas decorations and out of season clothes.
To me, it seems like a space that can easily be boundaried off from the younger kids. My husband however, is inconsistent. So the kids get confused about whether they're actually allowed up there or not. They go and wake him up sometimes just to get a toy that doesn't belong to them. He seems to think it's a rule for the sake of a rule, but I find it convenient to have a place I can hide things from them - and I find it stressful to not have one.
