But, alas, it's not where I want to spend my life.
Coincidentally, I gave my notice just last week, and have 2 weeks left. I've decided to go back to my true love, OB. There's a brand-new hospital opening up nearby, and I'll be working a 0.5 pm/noc position. I thought that the school schedule would be more family-friendly, but I spend my evenings and weekends playing catch-up with groceries, housework, homework, etc etc etc.
I grew up with a dad who hated his job, and a mom who spent her days at work and came home crabby. I don't want to set that example for my kids. We are fortunate to work in a profession that has such great flexibility. You gave school nursing a try. If your heart is in NICU and it will work for your family-- go for it!
