It would be a Obstetrician or Midwife. I would love for one day to run around my clinic office and the hospital. DOing emergency C-sections, when life threatening and necessary and catering to granoladoula attended births as desired.
I would love to study the physiology of the newborn and his system in adapting to the outside world. Comforting mothers in loss or grief (chas v`shulem), and helping women have healthy babies and births. Sharing in their simcha and using the medical knowledge to make rapid decisions.
