When Avalyn was in the NICU, a nurse told me that sleep was important to growth. She said that without proper sleep, my baby wouldn't grow like she should. From that moment on, it became my mission to make sure my daughter got the sleep she needed. It's also important that CF babies maintain a feeding schedule, so it definitely makes life easier when the sleep schedule is consistent!

And, yes, I am that mother that tiptoes around the house when her baby is sleeping. I'm not ashamed, she needs her sleep.
