Totally agree that it IS EXAUSTING to listen to, but the alternative would be so much worse. Don't give in, keep them in the rooms at nap (separate if possible) and tune it out! sooner or later, they will learn they are not getting out early, and more than likely go back to sleep OR lay quietly until nap time is over. Either way, don't sacrifice your peace and time to get chores done. Just tune it out!
