What is a potential consequence of babies sleeping in the prone position?

The potential consequence of babies sleeping in the prone position is indeed an increased risk of rebreathing carbon dioxide. When infants sleep on their stomachs, the position can cause their face to be pressed against the mattress or bedding, which may limit their ability to breathe properly. This can lead to a buildup of carbon dioxide in the immediate vicinity of their breathing space.

In the supine position, which is recommended for infants, their airway remains more open, and they can better manage their respiratory needs, reducing the risk of rebreathing carbon dioxide and potential suffocation. This risk factor is one of the reasons why safe sleep guidelines suggest that infants be placed on their backs for sleep to minimize the chance of sudden infant death syndrome (SIDS), which has been associated with the prone sleeping position.

Other choices, such as improved sleep quality, better digestion, or a lower chance of vomiting, do not directly address the physiologic concerns linked to the prone position and lack scientific support as benefits of that position in infants. Instead, they may reflect misconceptions about infant sleep rather than the risks associated with prone sleeping.
