How much milk does my newborn need?
Feeding my newborn
Typically a newborn baby needs about 45-90 mL (1.5-3 ounces) of human milk every 2-3 hours. If you are breastfeeding/chestfeeding you will not know exactly how much milk your baby is getting, but you can rely on signs such as weight gain, wet diapers (pees and poos) and baby's temperament (crying after feed). Your baby's doctor will also help ensure your baby is getting what they need. It is not possible to overfeed a breastfed baby and feeding on demand is recommended.
Attention should be given to follow recommended guidelines when feeding expressed milk or formula to avoid over feeding. The milk intake needs of your baby will change as they get older.
Babies may go through periods where they need more milk than usual. This is called cluster feeding and is usually due to a developmental milestone, growth spurt or to increase your milk supply.
