There is always debate how old a child should be when they can do household and outdoor chores. It all depends on your child and how much they can handle. Preschoolers can easily pick things up and put them back in their place. It teaches them the importance of tidiness. They can also carry their dirty dishes to the sink or dishwasher. Preschoolers can also lend a hand carrying recyclable items out to your recycle bin. They feel like big kids when they get to help.
