Switching laundry from washer to dryer (we have front loaders) started at 2.
Matching socks in the clean laundry (started at 1.5), then folding hand towels or washcloths (3). My 4 year old folds some of her clothes and helps put them away in her room.
Dusting with a swiffer duster ( they LOVE this, had to have 2 dusters or there would be a fight!) started at 1.5.
Putting away the clean silverware in the drawer, and loading the dirties back into the caddy for the dishwasher Started at 2 or the bigger kid, and my little guy followed suit at 1.5, though his sorting skills weren't as great ( I keep the knives out and put them in myself at the end)
Putting any used plastic dishes or cups into the kitchen sink for me. 1.5 year old loved this as soon as he could reach to drop them in!
Picking up their own toys, of course, from walking age , on!
Picking up sticks and putting them in the burn pile before Daddy needs to mow, walking age, on!
Throw Daddy's pile of dirty laundry (next to the bed), down the laundry chute ( since somehow , he can't manage to do that himself **Eye ROLL*). Started about 2 years old!
They love these, and getting to help in a big kid way is its own reward, they are always so excited to help, and of course they get a big thank you and hug or high five....they do get a sticker on their charts for "helping mommy" when they do any of these things in a day.
