One day, your child will need to earn a living. Kids can get an edge on the work world by starting
early and in doing so they will gain valuable experience working with different people. Also they can
learn about managing money-have some money to spend once they get older, or save for college.
But first ask yourself, is your child ready to work? Do they have the time, and won't it interfere with
their school work? If they are ready, then here are some jobs for kids to make money.
BABY SITTER
If your child likes younger kids, then a baby sitter is a popular choice. Parents often need a good
and reliable baby sitter________. This position can be even expanded into a baby sitting service, by
joining together a group of people who can offer babysitting services to all the parents in the
neighborhood.
PARENTS HELPER
A parents helper is similar to a baby sitter. However, if your child is too young to babysit on their
own, a job helping parents is a good opportunity. They can help watch someone's kids and assist with
the feeding, playing, or doing chores around the house. Later, once your child is older, they would likely
have gained some references for regular babysitting work.
HOUSE CLEANING
Instead of a parents helper, your child could simply do house cleaning. There are many chores that
would be suitable such as vacuuming, dusting.
CAR WASHING
Car washing is a needed service in many communities. Have_your_child_get together_with_a few_
friends to_offer_to_wash_local_cars. As an addition to this business, they can sell items such as coffee,
snack bags and donuts while people wait for their car to be washed. See what other professional car
washes charge in your area, and price the services competitively.
ANIMAL CARETAKER
If your child enjoys animals, then try an animal caretaker business. This might involve walking dogs,
dog washing, or general grooming.
HOUSE AND PET SITTING
If a neighbor is taking a trip or vacation, then taking care of their house and/or pets may be an
opportunity. This may include watering plants, and any other chores they may need.
