Those kids would just be picked last in dodgeball by the MD elementary kids.
Anyway OP, no ... I don't think there is a school known for matching into Peds. I wouldn't worry about matching Peds though. DOs have great match rates into MD and DO programs. Go where you want to and work hard!!
It doesn't matter what school you go to despite your interest..pediatrics is a field of medicine that will be conquered once you finish medical school. No school will simply put emphasis on peds and ignore rest of the imp part of your education. Also peds is one of the least competitive fields so you will be alright..just pass med school.
