Where I work the moms are kept in L&D for 2 hours after delivery. However, sometimes when things are busy they may pull a postpartum nurse to L&D to do recoveries. Of course, the recoveries are done in L&D and their staff is always nearby in case of any complications.
What my postpartum job entails: Assessments, pt education, pain management and LOTS of breastfeeding support. I work nights and that tends to be the prime time for breastfeeding meltdowns. Sleep deprivation, hormonal changes, and a baby who wants to cluster feed can really send a mom over the edge. Or baby is sleepy and does not want to eat and mom is worried the baby will starve to death. It helps to educate the parents in advance about what to expect from the newborn during the first 48 hours.
Pt education can also be a challenge due to time constraints and the abundance of visitors many moms have.
Also, we do a few newborn tests...hearing screen, transcutaneous bili checks, pre and post ductal O2 sats, required blood tests. And again, that can be difficult to get everything done when that abundance of visitors in mom's room are there to see and hold the baby.
I am sure there is much more, but I am getting a little tired and need to go to bed soon. Whatever you decide to do, I wish you the best!
