At night, babies should ideally sleep lying on their backs. During daytime naps or when supervised by adults, their sleeping position can be adjusted to prone. The baby's sleeping environment should maintain appropriate temperature, humidity, and lighting for sound sleep. The nursery should maintain suitable temperature and humidity levels, ideally between 26°C and 28°C (80°F and 82°F) with relative humidity at 50% to 60%.During summer months with increased mosquito activity, parents should also be mindful of the risk of insect bites in addition to room temperature.
Benefits of Tummy Sleeping
In the womb, fetuses naturally curl with their abdomen inward and back outward—a self-protective posture. This position provides infants with a sense of security during tummy sleeping, promoting deeper, more restful sleep and reducing wakefulness. It also supports healthy neurological development.Tummy sleeping also encourages babies to lift their heads and chest, strengthening large muscle groups in the neck, chest, back, and limbs while promoting muscle tone development. Additionally, tummy sleeping helps prevent vomiting and choking caused by stomach contents flowing back into the esophagus and mouth, and it alleviates gas buildup.pneumonia, excessive phlegm from colds or coughs, cerebral palsy, or certain pathological abdominal distension conditions such as congenital hypertrophic pyloric stenosis, duodenal obstruction, congenital megacolon, meconium ileus, necrotizing enterocolitis, intussusception, or other conditions like ascites, hematologic malignancies, kidney disease, or abdominal masses.
Babies with gastroesophageal reflux, obstructive airway abnormalities, or plagiocephaly may benefit from tummy sleeping to alleviate symptoms.Children with small chins, large tongues, or severe vomiting must sleep on their stomachs. Another critical situation requires special attention: when infants have phlegm, they often vomit. If vomiting occurs, place the infant on their stomach to allow food to drain out before lying them back down. Failure to do so may cause suffocation.
