Hey R., I am a former Woman's and Children's nurse and current pedicatric nurse. I also went from a critical care background to the W&C unit. I have never looked back! I can honestly say that being ACLS certified would be a huge plus. All of the L&D nurses where I worked have ACLS as a mandatory requirement. I would also say that at least 60% of the nurses on the floor had a critical care background. It is surprising how much it comes in handy. It will be much harder for you to step into a L&D position with no expreience. It would be much easier to step into a postpartum/nursery position and then cross train to L&D. That is what I did. I would say to play up the important parts of your critical care experience that are also very useful to L&D. Are you any type of BLS/ACLS instructor? IV/SWAT/Rapid Response/Code Team? Have you already looked into the IBCLC requirements and began working on them? If so, can you list that objective on your resume? Surgery experience? Experience with post-op is a huge plus as well. This is all I can think of off the top of my head. I will update my post if I think of anything else.
GOOD LUCK!
