How long after feeding can a baby take a bath?
Generally, it is recommended to wait 30 minutes to 1 hour after feeding before bathing an infant. Detailed explanation is as follows:

If the infant consumes a small amount of milk and does not experience significant spitting up or bloating during feeding, the digestive burden is relatively light, and bathing can be done after waiting 30 minutes. At this time, the infant's gastrointestinal tract has largely completed initial digestion, reducing the likelihood of discomfort caused by changes in position or abdominal pressure during bathing, thus minimizing issues such as spitting up or crying.
If the infant consumes a large volume of milk or has a weaker gastrointestinal system, making him or her prone to bloating or spitting up after feeding, it is advisable to wait for 1 hour before bathing. Sufficient time allows for more complete digestion, reducing the burden on the gastrointestinal tract and preventing worsening of spitting up or gastrointestinal discomfort caused by external stimuli when the stomach contents are not fully digested.
Prior to bathing, observe the infant’s condition. If there is spitting up or signs of poor vitality, the waiting time should be extended. Movements during bathing should be gentle to avoid pressing on the infant’s abdomen. After bathing, promptly dry the infant and ensure adequate warmth to prevent cold exposure.
