The sign that an infant is receiving enough breast milk is evidenced by steady weight gain and a satisfied demeanor after feeding. When an infant is adequately nourished, it typically manifests in a gradual and consistent increase in weight over time, which is one of the most important indicators of a baby's nutritional status and overall health. After feeding, a content and relaxed demeanor is also a strong indicator that the baby is satisfied and has received enough milk to meet their needs.

In contrast, frequent crying and restlessness may indicate hunger or discomfort rather than sufficient nourishment. Sleeping through the night without waking can sometimes misrepresent adequate feeding, as some infants may sleep longer for various reasons, regardless of their nutritional intake. Excessive spit-up after each feeding may suggest an issue with feeding or digestion rather than being a typical sign of adequate milk intake; while some spit-up is normal, excessive amounts could indicate a concern that requires attention. Thus, a combination of steady weight gain and a satisfied demeanor after feeding serves as the most reliable indicators of sufficient breast milk intake.
