The bottom line is-you are still a nurse, no matter how long you take off whether for fun, for kids, for family illness! There are times in our lives that we have to make choices. Will this possibly make it more difficult to get a job? Sure, maybe depending on the shortage vs. glut of nurses in the location that you choose to settle. Will it make it impossible? No.
I did not expect to take a year after my son was born, but I did. I also chose to work only PT and PRN positions for years after that choosing roles and situations that were best for him and my family, not my career. Has my career suffered? In some ways, I suppose, but I will "catch up" pretty soon and I will never, ever regret the time I took. There will always be patients and hospitals and nursing jobs, but sometimes, life and choices you make now are those "once in a lifetime" opportunities. If I hadn't taken the time with him, I would be regretting it now, for he is grown and will be leaving our home before I know it! I am a better nurse and a better administrator now for having taken the time I needed. This year will fly by, but this time growing with your spouse will last your whole life and, hopefully, strengthen your relationship for a lifetime on the "rollercoaster" together! I wish you luck and safe travels!
