D.N.
Actually, even if you show that you have someone 24/7 to be with the children, Air Force regulations prohibit a single parent from enlisting. They also state anyone with more than 2 dependents is prohibited. They always put the dependents first.
A woman I know had enlisted when she had a 4 yr old. But she was married and her husband was home. Her husband was killed in a car accident a few years later. She received an honorary dependent discharge or something like that since she was then a single parent and requested discharge so she could raise her son.
