I used to be a CNM, but it was too much with little babies, so now I'm at home full time.
I've worked two different jobs as a CNM.
#1 job was private practice. Me and 2 doctors. We shared call with another group of 1 doc/1 CNM. My practice was on call 2 weekends, then the other practice one weekend. Me? I was in the office 4 days a week (off every Monday, and we got off at 2pm on Fridays). I was on call every Tuesday and Thursday and 2 out of 3 weekends (Fri noon-Mon AM). Also, because I was the only midwife, if I had a patient that really, really wanted a midwife, I'd come in special for them on my off weekends or my off days during the week. I made rounds 4 days a week (Tues-Friday) on all the OB patients in the office, and on my weekends on call, I made rounds as well.
It was a LOT of call. We had privileges at 3 hospitals, and we frequently had patients in each one. We delivered about 20 babies a month. And, if they came on Tuesday, Thursday, or on 2 out of 3 weekends, I delivered them, unless they requested a doctor (rare). Every day, I'd leave my house around 6:30 to round at all 3 hospitals, then come to the office, work 8-4:30, then on Tuesdays and Thursdays, usually head back to the hospital to see about whoever was there, blah, blah, blah. I probably averaged 1-2 nights sleeping at the hospital every week.
Not every private practice job is like this. I was young, naive, and I got taken advantage of because I didn't know any better. But, I'm not the only one, either.
#2 was a clinic setting. We didn't make as much money as private practice, but we only worked 40 hours a week usually.
There were 8.5 midwives in that practice, along with 4 (?) doctors. There was one part time position. We averaged 2 days of clinic, plus one 24 hour call in a week. Some weeks were 5 days of clinic. Some weeks 2 days of call. We averaged 40 hours when looking at a month at a time. We had the post-call day off, but we really, really needed that day off. It was not unusual to get less than 30 minutes of sleep in a 24 hour call. That practice was BUSY. We delivered about 120 babies a month (just the CNMs). We saw all the walk ins to the hospital. We first assisted on every c-section. The on-call midwife made rounds on weekends. During the week, a different midwife made rounds (and we were so busy that rounds alone might take 2.5-3 hours).
This was med-wifey-ness more than mid-wife. But, on the other hand, we gave really good care to patients that probably otherwise would have gone without PNC because of money issues. So, it was a balance there. We did not have hours to sit at the bedside, nor 45 minutes to spend at a prenatal visit. However, all 9 of us did the best we could, and we all really cared about our patients. We had a low c-section rate, were VBAC friendly, nad about half of our patients went without epidurals. So, there were goods and bads. It was very rewarding know that we were making a difference. And very frustrating knowing that we weren't being good crunchy granola midwives. Trade-offs.
I hope this helps!! There are so many variations on how practices are set up. I think you have to ask a LOT of questions to find the practice that is right for you.
