NICU baby 35 weeks

Hi, I had gestational diabetes and my baby was born 35w 3d (6lbs 2oz). Initially she didn’t have to go to the NICU, however, she was tiring herself out from bottle feeding (my milk supply wasn’t coming in yet) and her glucose level went low enough that they took her to NICU. It’s been 3 days and although she’s improving, her sugar still drops to about the 50s when it needs to stay above 60s to remove the feeding tube and check if her body can maintain the required glucose level when supplemented by breast/bottle feeding only. It’s been tough because I get discharged tomorrow and I’ve cried my eyes out thinking about going home without her. I have major mom guilt and I wish I could just know when I’ll be able to take her home. For the moms that experienced something similar, how long did your baby stay in the NICU?
