I’m not sure if this is a hack, but it sure has made my life a lot easier since I’ve discovered it. Quite often I would wake up to a dishwasher full of DIRTY dishes that I had intended to run after the kids had their baths and were in bed for the evening. This never happens now that I have discovered my dishwasher’s delay function. After supper I get the dishwasher all ready to run, set it to delay 2 or 4 hours and press start. The dishwasher doesn’t interfere with bath time, and you can always add those last minute dishes before bed, and still wake up with clean dishes.
Anything’s can be good hack if it makes your parenting life easier. I have a delay function on my dishwasher and never thought to use it.
