Daniel can hear the words "wash" or "laundry" or "dirty clothes" from any room in the house. He even picks up on these terms when they are used differently, like 'Wash my hair" or "We need more laundry soap" or "Your clothes are dirty from the chocolate pudding".
He will run into the laundry room and shout, "UP!". He will also make washing noises and say "Wsh". He wiggles his hips and moves back and forth, a lot like The Twist, but we call this dance the Washing Machine dance instead.
His helping tower was in the laundry room, and it helped him perfectly reach to dump clothes in the washing machine. He is also able to put only one full scoop directly into the machine, no spills (a lot of practice!).
Usually these days we don't have to watch an entire laundry cycle, but we do need to check in on the laundry a few times when he hears the rinse cycle or spin cycle begin.
