A newborn should generally consume about 2.5 ounces of breast milk or formula per pound of body weight per day. For example, an 8-pound baby would need roughly 20 ounces daily

. Feeding amounts by age:

• In the first few days, newborns typically take 1 to 2 ounces per feeding every 2 to 3 hours

• By 2 weeks, this increases to about 2 to 3 ounces per feeding

• By 1 month, babies usually consume 3 to 4 ounces per feeding, amounting to about 24 to 32 ounces per day

• Feedings occur approximately every 3 to 4 hours, with about 6 to 8 feedings per day in the first month

Additional notes:

• Newborns may initially drink only small amounts of colostrum (around half an ounce per feeding) in the first couple of days, which is nutrient-dense and sufficient

• Feeding should be on demand, responding to hunger cues rather than strictly scheduled amounts

• Overfeeding should be avoided; most babies will regulate their intake naturally

In summary, a newborn's daily intake is roughly 2.5 ounces per pound of body weight, with feedings starting at 1-2 ounces per feeding and increasing to about 3-4 ounces by one month old, typically spread over 6 to 8 feedings per day.
