As for what is “normal,” it sounds like what we typically had to deal with when we accepted children under age 12, so maybe that’s normal.
Some of them did worse things, literally ransacked the house, and broke everything inside and outside that they could get their hands on.
It appears to be common for them to wet the bed, take the mattress cover off, stuff it under the mattress, and do it again.
We no longer accept children and if I catch anyone trying to smuggle them in they’re all out immediately.
It’s tough to rent a large house if you don’t accept children. You might consider dividing it into two smaller units.
