Part-Time 2nd degree BSN program?

I already have both my Bachelors in Social Work and Masters in Social Work but would like to eventually become a Nurse Midwife. I currently work in a hospital. By the time that I get to nursing school, I will probably have 2-3 kids. I would really prefer a part-time program. I have been thinking about going back to school for such a long time, and no time seems like the "ideal" time. I keep going back and forth thinking about how much I would regret being in an intensive accelerated 2nd degree program while missing out on my childrens' lives for those years. At the same time, I know that going back to school will require some sacrifices. I'm willing to take a longer time completing the program if it is at a slower pace.

Do part-time 2nd degree bachelors programs exist? I live in Southern California - San Bernardino/LA County. Once I get my BSN, I know that there are several CNM programs that are online which seems much more manageable to me. Also, if anyone has made it to CNM with a family, I would love any tips! Thanks!
