I had been a stay-at-home mom for 6 years when I applied for law school. I did not list it in my resume, but I did note it in my personal statement. I was accepted to almost all of the schools I applied to, and my not getting accepted into the others was due, I'm pretty sure, to my LSAT score (These were the schools that I didn't think I could get into in the first place but tried for anyway.). Don't worry about the gap in your education. I had little work experience out of college and was dealing mostly with babies for several years. Many of the people on admissions councils have children. They know how much work and dedication goes into caring for them. If you are a little older and have had real-world experience (including raising a family), schools are likely to be very much interested in you. You are not the average applicant. They might see you as bringing diversity to the class, seeing things from a different point of view than the average student.
P.S. I started out full time, but I switched to part-time after the first semester. I have two young children and wanted to spend more time with them. However, I know another mother of young children in my class who has found that the full time course is best for her family situation. I'm sure you can find a way that is best for you and yours. Good luck in your endeavor!
