Yes, we have some Isolette covers and use them whenever we can. We also have semi-private rooms with curtains, blinds, and closing doors; two babies per room max. This is WONDERFUL! I cannot tell you what a difference it makes- nighttime is silent and dark, just the way it should be. I SWEAR TO YOU: I came from a horrible place (developmental care-wise), and all of our babies had huge black bags under their eyes. I always thought that's just what NICU babies looked like, until I came to my new facility. These babies are SICKER, but look more rested. It's amazing. That's all the proof I need.
