I've got five kids and just finished 1L. Granted, the two oldest stayed to finish high school and did not move to school with me. That said I had 3 children living with me, ages at the beginning of 1L were 2.5, 4.75, and 14. I think I managed ok. However, I actually found law school itself much easier than the juggling of daycare/sick child care/teenage angst/family dram and law school. That, truthfully, kicked my ass. It was a tough year.
