Babysitting can be an interesting job. There is no limit in age to be a babysitter by law.  However having a good health is the first criteria for this career, it is because babies are very easily to be contracted by illness. Being responsive is another important requirement for babysitters. Babysitters have to know what kind of food is suitable or allergic to the kids.  They can never leave kids alone at home and at the same time to ensure all the kids play safety, even in the outdoors. Furthermore, Babysitters need to make the contact phone numbers of their parents available at anytime so that they can be contacted in case unexpected incidents. People working in this career are better to have First Aid training such that they can cope with emergency situations.  Strictly following the recommended family's rules and timetable are important, it is because regular eating time, playing time, sleeping time and entertainment time can assist children to understand the daily life principles.
