Sova på mage - ständiga frågan

"Studies suggest that stomach sleeping may increase SIDS risk through a variety of mechanisms, including:

Increasing the probability that the baby re-breathes his or her own exhaled breath, leading to carbon dioxide buildup and low oxygen levels
Causing upper airway obstruction
Interfering with body heat dissipation, leading to overheating

Compared with infants who sleep on their backs, infants who sleep on their stomachs:
Are less reactive to noise.
Experience sudden decreases in blood pressure and heart rate control.
Experience less movement, higher arousal thresholds, and longer periods of deep sleep."
