When my daughter was 2 we started letting her help us pick up stuff around the house. When she turned 4, I made a simple chart with pictures of daily chores and divided the chart into boxes for each chore type:
1. Getting up: tootbrush, clothes, potty
2. Pets: water, food bowl
3. Cleaning up before bedtime: dolls, blocks, trucks, books
We would put a smiley face in the boxes for each day she did those chores. Now that she's 6, we've expanded on the chart and put words instead of pictures and have attached an allowance to the completion of chores.
