Some are warm and friendly while others are formal and businesslike. The kind of doctor you feel comfortable being around will depend on your individual taste. The ability to listen and to allow you to ask questions, and a genuine tenderness towards children. If a doctor had to take every telephone call they would probably have no time to see their patients. You might want to ask how the doctor's office handles such calls.
Some offices provide a call-in hour in which the doctor takes calls directly.
You can narrow down your list of potential pediatricians by either speaking with their nurse or by requesting a consultation visit. Some doctors charge for a consultation while others do not. Ultimately it is up to you to select the pediatrician that makes you feel confident in their ability and comfortable in their presence. The better the relationship the better are the odds that your child will grow up healthy.
