Cluster feeding is a pattern of feeding that many newborns experience in their early months of life. During cluster feeding, babies tend to feed more frequently over a period of time, often in the evenings. It is normal and usually not a sign of any major health issue.
The exact cause of cluster feeding is not known, but it is believed to be a combination of biological and environmental factors. Newborns often go through growth spurts during which they need more energy from their mothers. They may also be using the extra feedings as a way to soothe themselves. Other possible causes of cluster feeding include lack of sleep, hunger, teething pain, and emotional needs.
Cluster feeding usually lasts no more than a few weeks before the newborn goes back to their normal feeding schedule. It is common for babies to experiment with different feeding patterns and schedules during their first few months of life.
