11. Dog Wash
Some doggie shampoo, a hose and a baby pool is all you need for this one. If you want to step it up, set up a blow-drying station, too, so pooches can have that “just stepped out of the salon” finish.

12. Sell Crafts Online
Help your kids set up an Etsy store to sell crafts like beaded jewelry and friendship bracelets. Etsy is a great e-commerce service that allows people to sell their own products online.

13. Start a Blog
Everybody’s blogging these days, and if your children have writing chops, they can too. What’s more, if the blog attracts a lot of attention, advertisers will pay to advertise on it.
