A 1-month-old baby typically needs about 3 to 4 ounces (90 to 120 milliliters) of breast milk or formula per feeding, with about 8 to 10 feedings in a 24-hour period. This means the baby will consume roughly 24 to 40 ounces in total each day

. Newborns feed every 2 to 4 hours, and breastfed babies tend to eat more frequently than formula-fed babies because breast milk digests faster

. Feeding on demand by watching for hunger cues like rooting, lip licking, or fussiness is recommended rather than strictly scheduled feedings

. In summary:

• Amount per feeding: 3 to 4 ounces
• Number of feedings per day: 8 to 10
• Total daily intake: about 24 to 40 ounces
• Feeding frequency: every 2 to 4 hours, feeding on demand

Always consult your pediatrician for personalized guidance, especially if your baby shows signs of hunger or fullness that differ from these averages
