My little kids love to help. So:
I bought an EMPTY plastic spray bottle and filled it with water! They spray the mirrors and walls and wherever mommy lets and then they wipe it all! Proud!
They also love to fold laundry. And you’ll be surprised how cute they fold everything. I let them sit on the bed and fold whatever they want while I’m busy in the kitchen.
(I redo everything later when they sleep :-))
