At what age should you let your daughter babysit?

Age 13-14: Prior to babysitting, a teen must be mature enough to complete a bls/ CPR course offered at your local fire department or hospital. It is wise to let a teen first be a mother's helper, or assist her in her first attempt. She must be able to feel competent handling emergencies prior to being left alone. Many factors go into when to allow babysitting, but age 13-14 is a typical age.
