Arin Solange has 4 kids and was tired of yelling for them, so she bought 4 wireless doorbells and installed the buttons for them inside a cabinet door in the kitchen.
There's one for each kid, with coordinating chimes in their bedrooms.
When she needs one of the kids to come downstairs, she just rings their doorbell.
And presumably, they come.
If not, well, there's always yelling.
Lots of people have commented on the video to share their high tech solutions too, like texting their kids from across the house (I do this all the time!) and using the “drop in” function to talk to them on Amazon Alexa Echo Dot in their rooms.
