Introduction
In general, it is beneficial for a baby over three months old to sleep on their stomach, as this position can provide greater sense of security, promote gastrointestinal motility, and relieve abdominal discomfort. However, if the baby consistently maintains this sleeping position over a long period, it may increase risks such as insufficient abdominal muscle tone or suffocation. Parents should ensure the baby's safety and appropriately manage the baby's sleeping posture.

However, if the baby consistently maintains this sleeping position over a long period, it may increase risks such as insufficient abdominal muscle tone or suffocation.

1. Benefits

Babies are accustomed in the fetal stage to curling up with limbs tucked and facing their mother's back inside the uterus; thus, this position makes infants feel safer and more comfortable. When lying on their stomach during sleep, gentle pressure is applied to the baby’s abdomen, which promotes intestinal movement and aids digestion. Additionally, if the baby has recently experienced abdominal discomfort—such as gas or indigestion—sleeping on the stomach may help alleviate these symptoms.

2. Drawbacks

If the baby sleeps on their stomach for prolonged periods, the abdominal muscles may not receive adequate exercise, potentially leading to reduced muscle tone, which could affect physical development and muscular strength. Moreover, there is a risk that the baby’s nose and mouth might become obstructed by bedding, plush toys, or pillows, increasing the danger of suffocation.

Parents should, while ensuring the baby’s safety, arrange an appropriate sleeping position based on the individual needs of the baby and guidance from healthcare professionals. If any abnormal signs are observed, prompt medical attention should be sought.
