Why Does My Breast Milk Spit-Up Look Curdled?
When a breastfed baby spits up, the milk may appear curdled or lumpy. This is a normal and common occurrence, and there’s no need to be alarmed.
The reason for the curdled appearance is that the breast milk has mixed with the acidic stomach fluid. When the milk enters the baby’s stomach, the stomach acid causes the milk to curdle or coagulate. This is a natural process and is not a sign that the milk has gone bad.
Babies tend to spit up more frequently than older children due to their immature digestive system. The lower esophageal sphincter, which acts as a valve between the stomach and esophagus, is still developing in young infants, allowing some of the stomach contents to come back up.
Other factors that can contribute to curdled spit-up include:
– Feeding the baby too quickly, which can cause the milk to mix with stomach acid before the baby has a chance to fully digest it.
– Overfeeding, where the baby takes in more milk than their stomach can comfortably hold.
– Acid reflux, a condition where stomach acid flows back up into the esophagus, causing discomfort and spit-up.
In most cases, curdled spit-up is not a cause for concern unless the baby seems uncomfortable, is losing weight, or is spitting up excessively. If you have any worries, it’s best to consult your pediatrician.
