Most states do not specify a minimum age for babysitting, and most do not have laws regarding babysitting. However, states offer guidelines and recommend that a babysitter be at least 13 years of age, according to Babysitting-Rates.com.
While the age of a babysitter isn't set by law, states do have laws outlining what constitutes child neglect, which include irresponsible child care practices. Most parents take into account the maturity level of a babysitter or older sibling when determining whether to leave younger children in his or her care. WebMD.com recommends considering factors such as crime rate, neighborhood setting, use of an alarm system, and individual comfort and maturity when selecting a babysitter.
