Babies born at 34 weeks what is ur experience?

I am currently admitted in the hospital for severe preeclampsia and have to stay until my baby is born on April 8th. When he is born he will be 34 weeks old and he is already in the 70th percentile for his growth. I am currently on high blood pressure medication labetelol And it seems to be working. They absolutely will not let me pass 34 weeks so I am wondering if anyone has had a planned delivery at 34 weeks and if you had the baby vaginally or csection and how long did the baby stay in the NICU and what were the reasons for hisnor her stay.
