How to become a part time caregiver
First you have to like to be around seniors or children.
If you don't like either it would be a bad idea for you to be looking after them. They will likely be able to tell and not want you to be near them.
Then you can check out any daycare or senior programs in your area. Even in small towns, there is usually at least one program for senior citizens, and sometimes many for children.
