If you are actually with your infant, breastfeeding is generally easier than bottle feeding since there is nothing to prepare and no equipment to wash. But if you are at work, no matter what kind of job you have, it is important to acknowledge that prolonged breastfeeding can be really challenging. Specific barriers to sustained lactation that working doctors routinely face include inefficient clinic sessions that run late right through lunch or dinner, long and busy shifts including overnight call, managing prolonged labors or unstable patients, performing lengthy operations, and lack of time, period. Scheduling conflicts and stressors can affect milk supply.
