I think I had a pretty cushy NICU experience. I was allowed to hold my boys as much as I wanted. They always breasted. They weren't sick nor was there anything seriously wrong with them.
That being said here's my tips for staying in the NICU
1. Have your computer to watch some show on. I watched so much Friends while there. While I pumped, Friends was on, it made the time go by so much more quickly. My room didn't get internet so I couldn't do much online unless I used my phone. (I bet you anything I'm going to get arthritis in my fingers and thumb when I'm old…"
2. Have a long chord for your phone to charge it
the boys' side
Turn around and there's my side. I had a little curtain I could pull back and forth for a little privacy
4. Wash and sanitize your hands endlessly. This was our sink area (they put their weights on the wall for us each night)
7. Read your scriptures, the Ensign, and conference talks. Oh man, I teared up and cried almost every time I read anything. The words I read in those pages and talks lifted my soul each time and reminded me I am not alone through it all, that Christ was feeling my pain. I was reminded that everything is done in the Lord's timing and His will is more important than mine. I read talks on overcoming trials. I happened to read Ensign articles that spoke of other's experiences of their babies in NICU worse off than mine. I was always so inspired by everything I read, I knew it was the Lord's way of helping me through this time.
