Interviewing for a position as a CA for a large peds hospital!

I am looking for some tips. I am currently a PCA with 3 years hospital experience. I was on the cardiac unit for over a year and have been in the float pool(ICU/ED/MEDSURG/PSYCH/CCSU) for nearly two. I am interviewing next week for a PCA(CA) position in a pediatric hospital. My only experience with peds are my own children(9 and 11), some ECE credits I earned a million years ago and my work in a bereavement group that supported parents who experienced miscarriage and stillbirth. How can I impress the nurse managers? Any words of advice or wisdom?
