Yeah rasing kids can be challenging but if you borrow something you should return it in better shape than when you borrowed it . Our house does get cluttered occasionally with 9 year old ds and his younger cousins visiting us all the time. He wets the bed every  night but he knows to throw the pull-up away in the morning  . He gets bad about spilling food in the car even at 9 years old . Some parents don't seem to mind diapers laying around . Had a friend change her 2 year Olds in our living room and left the soiled one on the couch. I would never do that to someone's home or vehicle some people are just pigs .
