A Good Night's Sleep???

Last night Bryn looked into our smoke detector issue. It must simply be an old detector as it did NOT have a back-up battery in it. So, he disconnected it & we'll purchase & install a new unit this weekend. After getting that one disconnected, we were guaranteed a good nights' sleep, right? Wrong! Incredibly, at 2:13 a.m., the detector in OUR bedroom started chirping & woke us up! My initial thought was that it was still the hallway detector, but how could that be? Then we listened more closely & discovered that the chirp was a little louder than it had been the past 2 nights. So...today I will be running to Target & buying a bunch of 9-volt batteries to replace in ALL the smoke detectors so this doesn't keep happening! Here's to a good night of sleep tonight...I hope?!?!
