So, I asked my friend and her reply was basically that "no one worries about it" and it's not seen as "limiting". Given my (current!) plan is paediatrics with a back up of psychiatry, and neither are in the intern rotations, I asked about them specifically, and her reply was that both are well covered in PGY2 (up to 6 months), and that it's possible to do the whole 12 months of PGY3 in those areas.
I don't know if that really helps? I might tag a few regulars who've done intern years and hope one or two of them might be available to provide their
thoughts at some stage (
