A newborn baby typically drinks about 1 to 2 ounces (30 to 60 ml) of milk per feeding during the first week after birth. By the end of the first month, this amount increases to about 3 to 4 ounces (90 to 120 ml) per feeding, with feedings occurring roughly every 3 to 4 hours. This totals to approximately 32 ounces (960 ml) per day by one month of age

. Breastfed newborns usually consume similar amounts, starting with small volumes of colostrum (up to half an ounce per feeding in the first days), then increasing to 1 to 2 ounces per feeding in the first week, and 2 to 3 ounces per feeding by two weeks old

. As the baby grows, the volume per feeding increases, and the frequency of feedings may decrease. By about 6 months, babies typically consume 6 to 8 ounces (180–240 ml) per feeding, 4 to 5 times a day

. Overall, a good rule of thumb for formula feeding is about 2.5 ounces (75 ml) of milk per pound of the baby's body weight per day, but it is important to follow the baby's hunger cues rather than strictly adhering to fixed amounts

. Summary:

• First week: 1–2 ounces (30–60 ml) per feeding, about every 2–3 hours
• By 1 month: 3–4 ounces (90–120 ml) per feeding, every 3–4 hours
• By 6 months: 6–8 ounces (180–240 ml) per feeding, 4–5 times daily
• Total daily intake around 32 ounces (960 ml) by 1 month
• Feeding on demand and watching hunger/fullness cues is essential
