Probably some of you have other good ideas?!
You've picked up on this already with the laundry. Kids LOVE to learn and help with things. It often will take a lot longer in the beginning, but over time you'll really appreciate this investment in skills as they grow older.
Another thing that I love about the Montessori approach is that it's all about building intrinsic motivation in kids. They need guidance, obviously, but instilling in them a self-directed motivation is amazing.
Probably the most important thing is spending some time on your environment. Do they have cabinets accessible where they can get their own plates and toys etc? Yours is still young, but they grow quickly! The more your environment is set up to make self-directed play and "work" accessible to them, the more they'll do it.
