Placing a baby on their stomach in the prone position can help them breathe more comfortably. With the chest facing down and the back facing up, this position takes pressure off the lungs, allowing for better oxygen exchange and helping fluid drain more effectively. In a randomized clinical trial, named PROPOSITIS, researchers investigated whether the prone sleeping position could help very young babies with a lung infection called bronchiolitis, not to be confused with bronchitis.
