Law School Discussion

I'm considering becoming an attorney but also want to stay at home with my children when they are young. Is it likely that a woman could return to work as an lawyer after many years off? Are there any specialties that might be better for this than others? I might not mind working a few hours a week maybe as a volunteer or paralegal during that time. If I took time off and then was rehired would I probably start at a salary that is lower that it was when I quit the previous one? Thank you for the answers.
