Need Advice about Career

I am an RN and I have been one for a year now. I've tried adult med surg and I hated it. I am now working in a pediatric ICU. There's days that I don't like it and other days that I do. I'm pretty much indifferent about it. It's not my dream job but I don't hate work. I've been talking to my manager about my feelings and I'm stuck on making a decision so hopefully some of you can help me be my voice of reason. I can either stay in pediatric ICU, become more experienced, and hopefully I'll end up liking it even better. Or, I can test the waters with labor and delivery which I've wanted to do for awhile. Keep in mind I have only been in pediatric ICU for six months. I would hate to leave so early but I'm stuck. Pros and Cons: pros of staying in pediatric ICU is that I'll get more critical patients here soon. I love my coworkers. I like my schedule and my manager and my pay. I like the kids I work with. Having a year or two of experience can be really beneficial later down the road. I just don't know if I'm too happy with an ICU, because it's terrifying at times. Cons include traffic to going downtown, parking, it's not something I want to do forever, it gives me a lot of anxiety and stress, and I feel like I'm wasting my time sometimes because I could search for other opportunities like labor and delivery which is something I've always wanted to do yet haven't tested out. There's a few positions open and idk if I want to miss those opportunities. So with all that being said, what do you guys think?
