My daughter was born 6 weeks early and is in NICU. The staff have this cd in a cd player near her bassinet and I play it on repeat the entire time I'm there visiting. Even on low volumes I feel it gives both of us something else to focus our listening on (instead of all the bells and alarms). It definitely helps to keep her calm and when its on she engages in "quiet alert" for longer periods of time. It has been a blessing to get to use this cd in the NICU and I plan on ordering it to have it at home.
