Some pediatricians work in hospitals or emergency rooms as "pediatric hospitalists". Their day begins early with a review of the new patients that came to the hospital and were "admitted" overnight to the pediatric service. They see each patient at least once a day and then spend most of the rest of their time deciding on their patient's plan of care (what tests, medication, surgeries or other treatments their patients need to get better). They then interact with specialist consultants, nurses and medical technicians to refine their plan and put it into action. Throughout the day, they check on the progress of their patient's plan of care, making sure they are getting the expected response to treatment and results from tests, and adjusting their medication as needed. They usually head home in the evening, but might need to be available to receive urgent calls about their patients, and might sometimes have to return to the hospitals for emergencies.
Pediatricians who work in ambulatory clinics usually have more regular schedules. They have a "patient panel", a group of patients that they see regularly. Their daily schedules are usually planned in advance with some flexibility for cancellation or drop in appointments. They focus on managing the long term care of their patients, making sure that they remain healthy and get all the preventive care they need.
