Question
My baby is three months old, and he always sleeps on his stomach during naps. Is that normal?
Answer
Babies naturally adopt a curled-up position with their bellies to the inside and backs to the outside while in the womb, which is the most natural self-protection posture, making them feel secure and easier to fall asleep. Sleeping on the stomach helps with the growth and development of the nervous system and strengthens the large muscle groups. Moreover, it can prevent discomfort caused by food from the stomach refluxing into the esophagus and mouth. However, as babies grow, it’s important to help them change their sleep position to avoid habitual stomach sleeping.
