I remember seeing a blog post somewhere about great chores for certain ages. I will find it for you. My DS is almost 4 and he makes his bed (with my help), puts his shoes away, picks up his room, puts away the silverware out of the dishwasher into the drawer when I unload it each day. He "helps" with whatever cleaning I am doing.. I usually spray the dust cloth with my Mrs Meyer's cleaning solution & have him go about dusting furniture.
Happy wife & homeschooling mama to J (6) and N (3) & Little J(1)
