alarms in his older brother's room as a prank. It was loud enough that it woke up my wife and me, but not the prankster who has a room down the hall. The first alarm started at 4:30am, and they continued every 15 to 30 minutes after that. Here's the thing, the first two were on the Alexa speaker that is normally in his room. I unplugged it after the second alarm and thought I had it fixed. The last three were on other speakers hidden around his room.
I don't know what the older son did to deserve the prank, but I fear this will escalate further unless we can sell one of the kids.
