How Long Does Breast Milk Digest In The Baby’s Stomach Until It’s Empty?

Hello, I have a 3 month old baby whose spit up is bad even though it’s always burped. Even when he was sleeping … the condition he had been drinking breast milk 2 hours before and he immediately fell asleep afterwards, he often slept badly because of stuttering like going to spit up, and finally spit up spurting out of his nose too even though he was sleeping. What I want to ask, is that within 2 hours the ASI that he had been drinking and brought to sleep had not yet been digested? Is it natural that in a sleeping position a baby can spit up even to burst from his nose? When should I consult a doctor directly if this is not normal? thank you

Hello. Thank you for the question submitted to HealthReplies.com. We can understand the concern you feel.


The average half-life of gastric emptying in breast-fed infants is about 47 minutes. After 1 hour, an average of 29.5 mL of breast milk per 0.1 m2 of body surface area was emptied from the baby's stomach.


Spit up is the release of some milk when or after the baby is suckling. This is a normal thing that often occurs in infants up to 1 year of age. Usually spit up in the form of milk that flows with varying volumes, generally around 1-2 tablespoons. Most episodes of spit up in healthy infants last less than 3 minutes and occur after feeding / feeding. Different from vomiting, babies who experience spit up still look active, comfortable, gain weight well, and there are no respiratory problems. The main reason for spit up is the baby's stomach size which is still very small and the valve is not too strong. Therefore, spit up usually occurs when the baby drinks too much milk, when belching, or swallows a lot of air when drinking too fast or crying.


Meanwhile, vomiting is a complex process when food / drinks are forced out of the stomach. Vomiting requires the baby's effort to pass milk so that the baby who is vomiting will appear to be straining, uncomfortable, or fussy. The majority of causes of vomiting in infants are abnormal, for example gastroesophageal reflux disease, intestinal obstruction, cow's milk allergy, or hereditary metabolic abnormalities.


If your baby's complaint seems to interfere with the process of breastfeeding, you are advised to immediately check your baby to a pediatrician so that the cause of the complaint can be identified and given appropriate treatment. It is hoped that later there will be no further disruption in growth in children.


In addition, it is recommended that you help burp the baby if it appears to release the milk provided. The trick is as follows:

Carry the baby facing back and the baby's chest is positioned on your shoulder
Support the baby's head with your hands
Gently rub the baby's back until burping
