What should I do?

I have been a nurse for almost 2 years now. I have worked as a school nurse, did flu clinics, spent a short time on post partum[had to leave r/t health reasons] and now home health/private duty for past 8 months. I like home health and plan on keeping one of my private duty pediatric clients for a few hours/week. But, I need to make a change. First, prn private duty pays well, but, no benefits and very unpredictable with hours. Second, would like more of a challenge and would love to actually have sick and vaccation time. I have been offered a position on a surgical unit 7a-7p, 3 12's. My first love is Maternity/NICU, but positions are very hard to come by and when openings exist, they are usually filled from within or want someone with tons of experience. Anyway, thought I would start on the surgical floor, gain some acute experience and wait to see if a position opens up on maternity and then go for it. I am a little nervous about going to a surgical floor, r/t all the horror stories told about med/surge. Also, not sure if it will be too much going back to nights and 12 hour shifts, since I have never worked a 12 hour shift in the hospital before. I am so confused about what to do. I also have the option of working OB in a community health center for three days a week, and keeping my private duty for the rest. I have been so undecided about this and don't want to make the wrong choice. Any help/suggestions would be greatly appreciated. Thanks in advance
