I think that as soon as they are old enough to understand what you are asking of them, they are old enough to help out. I have a 3 and 5 year old, both of which have been helping out with small things for quite some time. They started cleaning up their own toys when they weren't even 2 yet. They try to fold and put their clothes away for me, will dust, wipe down the table after dinner, give the dogs baths, feed the dogs, pull weeds, water plants, or wash the car. Of course, many of these things are going to require that my husband or myself help them or go back after them to redo it, but at this age, it's about teaching them to do their share in keeping the house clean or orderly. They love to be able to help out, and often ask to do so without being prompted. Often times, my husband and I will give them a little bit of money to go in their piggy banks, but we are more trying to teach them responsibility. It's not about the money.nThe only 'chore' they have is to keep their toys picked up in their rooms. I think that all children should be required to care for their own room, and not depend on their parent to do it for them. We are also adding 'feed the dogs' as a chore that they alternate daily. For other chores, such as taking out the trash or vacuuming should wait until they are big enough to do so without making a larger mess or hurting themselves. This will depend on each child. My oldest is very coordinated and could probably handle chores sooner than our youngest, who is very clumsy like his mom. Just take into consideration the abilities of each child and don't assume that because one can handle it, they all can.
