There are many things that your children can do to help you around the house. My children have produced a video to show you how they help me around the house at Christmas.
If you are looking for activities to do with your children, that are a little more, well, constructive than these, you can find an advent calendar at the bottom of this page. Just click on today's or any past day's square and it will take you to the activity for that day! Have fun and God Bless!
