@pheonic Hello! My twins were in the NICU for a month and I'm also in the process of a career change to nursing (taking prereqs right now).
Our nurses were for the most part amazing. We did have one or two that we really loved and asked that they be assigned to us whenever they were on shift.
One thing I really admired while interacting with them was the mode-shifting they did so readily. They interacted with the babies, us, and each other so differently. They explained that the babies were their patients, but so was the whole family, and so their job was the baby first and us as the parents second. Also, as queer parents, there was absolutely ZERO issue or discomfort and that's so important.
To answer your specific questions:
1) The nurse who sticks out the most in my mind and who we immediately asked to be our main nurse was just very nurturing. She would talk to our babies like people, tell us that when we came in the door the baby's head popped up at the sound of our voices, and generally just made it clear that while she was a professional who knew what she was doing, we were the parents and that was something different and special to our kids. She was very reassuring and never made us feel like our kids didn't deserve her full attention and care just because they weren't sick (they were feeder-growers, no other health concerns).
2) One thing I would have appreciated that me and the occupational therapist realized after a couple of weeks was that the pressure to nurse/breastfeed began to supersede the importance of me being there to cuddle my babies. I realized I was caught between "I want them to eat" and "I want them to breastfeed" and the worry and anxiety over that became the focus, instead of "I am here to be with my children and give them skin-to-skin time." I wish that hadn't happened. I wish the focus had remained on "we'll try to breastfeed, then they'll eat from the bottle/ng tube, and you will cuddle the crap out of the baby." It was subtle, but it did happen, and it shouldn't.
3) One nurse made us feel like super incompetent parents. It was subtle, but I was a week and a half out from a c-section and my wife had had to return to work and save her leave for when the kids came home. We/I were exceptionally vulnerable and stressed out and already felt like we weren't capable of handling our tiny, fragile children. It was a simple interaction. The baby started to brady and turn blue. And she basically snapped at us about paying attention to the baby and not the monitor. Which is legit - you don't have a monitor at home. But imo she should've handled the immediate situation - the baby was not breathing! - and then walked us through it afterward. It was a short, small interaction, but I still remember it and I still don't like that nurse.
4) As with any time you have a patient, your patient is at their most vulnerable and treat them as such. Be very reassuring and exude the confidence we don't feel. Remember that, in addition, the parent who gave birth is recovering and super hormonal and might have been cut open to get that baby(ies) out. Vulnerable is the word here. Everyone's emotionally and physically vulnerable and you are the caretaker of that situation while you're on shift.
5) I don't have any other advice but I will say I was delighted every time I was told how beautiful my babies were. Any little bit of personality or uniqueness was appreciated - y'all see tiny babies all day. This one's mine. Tell me she's special, even if it's a lie. I'm at my most vulnerable and went through An Experience and I need to hear it.
Good luck! I hope to join you in this journey from the nurse end in the next few years!
