Needing some reassurance 😓

I just delivered my baby girl yesterday at 29w1d, she weighed 2lbs 12oz, tonight was the first time I got to see her because I was on a magnesium drip due to severe preeclampsia. When I saw her, it tore me apart how tiny and fragile she was. I’m so worried about her. I just needed some reassurance from maybe some mamas who have gone through this before. Maybe some tips on how to get through it and what to expect? Also how long was your NICU stay? Thank you in advance 😣
