This comment is somewhat related. I hope it is helpful. I know a young lady who started law school when her son was three. She is a single parent, and she commutes two hours each way to school everyday. Despite all of this she made law review and is in the top 15 of her class of 250. If she can handle a child in law school, so can you. However, the experience may be more difficult than you would like. I would be less concerned with underperforming in law school than I would be with missing some of the most special moments of your child's life because you are very busy as a 2L. Unless your going to someplace like Baylor, waiting until the summer after your second year may have less logisitical problems. Although doing so would likely result in you not being able to participate in a summer associateship during your second summer, but if you plan on being a government attorney the costs of this missed opportunity would be diminished. I wish you luck and I admire your rational concern and your motivation.
