What a great goal to be a peds nurse! It's such a rewarding career! I work in a primary care pediatric practice, so I would say the most rewarding thing is to feel as though I am an integral part of my patients care and I love being able to watch all of the children grow. Families come in so many time during the first few years of life so you really get to know this families on a deeper level. Luckily in private practice I don't have to deal with too much bad news , but we have lost a few patients and that will always be the hardest part. I truly wish you the best in your goal to becoming a pediatric nurse- it is truly a blessing!
