not to worry...many units (not just the NICU) have the pecking order, which is established by nurses showing their skill level and professionality, which also only comes with experience. I know it is hard to be at the bottom, but as other posts have said, do your assignments, watch others, and be willing to absorb as much knowledge from the more seasoned staff. Usually, the more seasoned nurses take kindly to someone willing to learn, and they do afterall have an abudance of knowledge for you to tap into. You will see that after a while, you won't feel like such a newbie. Hang in there, keep loving your job, and soak up all you can!
