New grad on postpartum

Hey y'all, I've recently accepted a job on a postpartum floor, and I begin orientation in a few months. I precepted on this floor, so I'm really familiar with it, but didn't get as much hands on experience as I would like due to my preceptor. I'm worried that once I begin orienting to the floor, I'm going to have a hard time adjusting. How long did it take you fellow PP nurses to get comfortable with your patient loads, assessments and just the general flow of the shift?
