1. Try to assist a peds resident with their research project at your school. Good way to meet the other residents/faculty/etc.
2. Externships (I visited three or so back in the day). Externships are two sided; can be super helpful or hurt you. Dependent on if you are courteous/respectful/engaged vs. annoying/any bad quality you can think of.
3. Pediatric focused volunteering (give kids a smile, non-dental children related volunteer opportunities)
4. Shadowing pediatric dental offices (good to network and sometimes they may be affiliated with a program as an adjunct faculty which can lead to a good rec letter).
5. Reach out of pediatric faculty at your school and talk with them about how to improve your chances and their thoughts on what a constitutes a good applicant.
**Programs are looking for those that are interested in working with kids, how they have demonstrated that through their activities and that they are academically qualified to pass the pediatric board exams.
