You would broaden the appeal of your application with exposure to other age groups. After all, for most of your clinical years you'd be required to have interactions with adult patients. I agree it would be fine to do this through shadowing experience.I still have a bit of time before I apply, but I was wondering it would be an negative aspect if most of my activities were concentrated in one area. All of my clinical and nonclinical volunteering is in pediatrics and child focused (NICU, PICU, Tutor for at risk youth) Should I volunteer in another area or am I good with my interests in pediatrics?
