Understanding appropriate portion sizes helps ensure babies get enough nutrition without overfeeding. Younger babies may only eat a few spoonfuls, while older babies gradually increase intake. Babies are good at regulating hunger, so caregivers should follow cues rather than fixed amounts. Portion sizes vary depending on age, appetite, and growth rate. Offering small portions and allowing seconds if desired encourages healthy eating habits. Respecting a baby’s hunger and fullness signals builds a positive relationship with food.
