During the first week of life, a full-term newborn typically consumes about 1 to 2 ounces (30 to 60 ml) of breast milk per feeding. This is because their stomachs are very small at this stage

. More specifically:

• On Day 1, a baby may get only a few drops to about 5 ml (1 teaspoon) per feed.
• By Day 3, this increases to about 15 to 30 ml per feeding.
• By Day 7 (one week), the baby's stomach capacity is roughly the size of an apricot, holding about 45 to 60 ml (1.5 to 2 ounces) per feeding

Mothers often produce around 500 ml (16.5 ounces) of milk per 24 hours by the end of the first week, supporting these feeding amounts

. In summary, at 1 week old, expect your baby to take about 1.5 to 2 ounces (45 to 60 ml) of breast milk per feeding, feeding approximately 8 to 10 times per day. This volume will gradually increase as the baby grows
