Hi OP, You sound like you are really hoping to take care of some sicker babies. I can tell you from experience that firstly getting along well with your nursing team will make you a shinier candidate to begin to work with sicker kids. After your stable babies are well cared for you could ask some of the nurses with sick kids if they need help. Pick up extra shifts and cover sick calls. Ask your unit director if there are any evidence based research topics you could look into for the unit. Focus on safety and safe medication administration. Happy, safe, helpful nurses get promoted. Even young ones, trust me. I know.
