NICU time at 34 weeks delivery?

Our di-di twins surprised us and arrived at 33+6. I started having natural labor but we still ended up doing a C section. They are doing very well all considered, and were born a nice 5 lbs 4 oz at birth despite the early arrival! They are in the NICU for lung support, but they’re allowing skin to skin and our son came off the CPAP today! I’m curious if anyone has thoughts or experiences about how long to expect them in the NICU. as I recover from the c section it’s nice to have them in good hands honestly. I’ll be discharged from the hospital on Monday.
