I am not a pediatrician, but I work as an occupational therapy assistant at a pediatric therapy clinic. Hours with this population largely revolve around school. During the summer, I tend to work 4, 10-hour days (8am-6pm). During the school year, I work 3, 10-hour days and 2, 5-hour days. After school appointments are most sought after, so later availability is important in my industry.
However, with therapy, these are regular weekly appointments. For a pediatrician, they’re more one-time appointments where kiddos can probably miss school. It all depends on the nature of the job you choose with the pediatric population!
