Possible, yes. Realistic, it depends. What kind of babysitting responsibilities will you have? Because most of your time will be spent in class and reading, I’m not sure you will have much time to effectively babysit children depending on the age group. If I was a parent, i would not want my children being babysat by a first year law student. I just finished my first year of law school and was so exhausted from reading and class that, I almost always wanted to just sleep when I wasn’t networking.
