Dilemma

Hello everyone,
HERE'S THE CURRENT SITUATION-I am a new RN and have landed a job working Med-Surg, eventually requiring me to work with PEDS patients and floating to god knows how many floors throughout the hospital-ortho, neuro, tele, etc..... I was desperate at the time to get a job, because I passed boards and got married in July, moved to the west coast in August, and was just content being a housewife until after the holidays. After the holidays, I was ready to job hunt (plus pressure from the hubby,ha). This hospital had the most opportunities at the time as well as FT positions, which I needed. I applied thinking that I was just going to be on Med-Surg, but nope. Okay, so I took the position anyway, just to get my foot in the door and start my career. I've been orientating for 2 weeks.
HERE'S THE DILEMMA- A program came out just after I got hired to train for peri-op nursing. Six months training with a 1-yr. internship and a 2-yr. contract. I feel I was made to work as a scrub nurse and I am fascinated with surgery! I told my current mentor about this and she said to stay with my current position for at least a year before going to a specialty! I don't want to eventually work with kids! I feel if I pass this opportunity up, it won't come around again, (and it's in the best interest of the company). But, I just got hired as a new RN with no experience, I feel like this will go against me. What should I do? Thanks to anyone who can provide insight.
