update: I now have 1 peds elective - a subI in NICU - hope thats enough to prove myself, cuz the rest are internal
You should be fine
The best thing I can tell you is to get a Peds adviser at your school ASAP. You'll need to apply broadly, but they can help you determine the tier of programs you'll be competitive for and how to work around your lack of peds rotations (which, again,
with emphasis, I don't think is a huge problem).
As for the NICU, start looking for resources now. I don't have any particular recs, but there are threads on SDN that give options. UpToDate is also reasonable starting place - read up on BPD, NEC, IVH, ROP, feeding protocols/fluids, PDA physiology, Pulm HTN, and ventilator management. If you can have an idea of what those things are, you'll be good for a student.
Other than that, the biggest thing I can tell you is, if possible, always find the baby's nurse and ask if they can help you handle the patient/examine. Many NICU's are very adamant about clustering care, and NICU nurses are overprotective particularly when people they don't know show up. Play up your inexperience and let them show you how to do things the way they like them to be done.
