I left nursing about fours ago to stay at home with my newborn and my two other children, both under the age of five at the time. I was only in nursing for three years before I decided to stay home with my children. My experience is in OB and NICU. I would like to go back to work and stay in this area of nursing. All the articles I read say take a refresher course, but I have only been out four years, do I need that? The refresher courses in my area are strictly medical/surgical. Any advice would be appreciated.
