DC1 - exH, OB/Gyn doctor, nurse for me, nurse for baby, and anesthesiologist for my epidural at one point;
DC2 - exH, doctor, two nurses, at least twenty other people (medical students at varying stages of their studies and OB/Gyn residents). I squeezed the hand of one resident really, really hard. This particular baby was a chance for the students to see a vacuum extraction. A nice Scottish anesthesiologist arrived five minutes too late, apologised profusely for lack of epidural, congratulated me on a bouncing baby, apologised again when told exactly how 'bouncing';
DC3 - exH, hospital OB/Gyn resident, two nurses, flustered lad from phlebotomy (temporarily) until I told him to get out, my OB/Gyn doctor for the last hurrah (to direct the mopping up);
DC4 - exH, hospital OB/Gyn resident, a seasoned nurse called Roxanne who knew a woman whose DCs went to my older DCs' school (we chatted as the Dr waited for the placenta and then stitched me back together);
DC5 - exH, midwife, trainee midwife.
