Medical personnel run the gamut from enlisted corpsman or medics to flight nurses and trauma surgeons. Being able to pump while working in the medical field depends very highly on your job and not so much your rank. Finding a place to pump is fairly easy. Most medical and dental personnel should not have any problem finding an unused space to pump in. Hospitals and clinics have spare examining rooms and offices, and oftentimes a pumping or lactation room has already been set up, you also have the option of visiting the Mother/Baby unit and using the pumps there, as long as you have your own collection kit.
Finding the time to pump depends very highly on your specialty within the medical department. Personnel working in administrative positions or as providers in clinics (especially OICs) will find pumping easier to manage than a nurse working in the ER or L&D. It is more difficult to find the time to pump simply due to the chaotic nature of the job and the constant stream of patients. 12 or even 24 hour shifts (for providers) are the norm in medical as well, making it important to add another pumping to your schedule if at all possible. Like many of the other job specialties in the military that often have unexpected changes in schedule, it is important to pump when you get the chance and not necessarily wait for your next scheduled break. If you are an EMT or paramedic, take a look at the First Responders page for more information.
I am a Navy nurse, so I squeeze in pumping at work about every three to four hours during a 12 hour shift. Since I am at a large hospital with a NICU, there are private pumping rooms available. The Navy also has a policy that requires members to have a place to pump that is private and not a bathroom, as well as a place to store milk and adequate time to pump. They emphasize that allowing mothers time to pump will decrease the likelihood of the mom having to take off work for sick children. I have been in the Navy for 11 years, have had three children, and breast fed and pumped at work for all of them. Lt. j.g., Navy
Medical personnel work with various drugs and other agents that can be harmful to your baby if passed on through your breastmilk. Be sure to check with your Occupational Health representative, especially if you work with anesthetic gases (nitrous oxide, halothane), antineoplastics, or radioisotopes, as all can pass through breastmilk (see the HAZMAT page for more information).
Medical personnel can certainly continue to breastfeed while on the job, and in fact, can be at the forefront of modeling this healthy behavior to their fellow co-workers and patients.
