(Younger babies with smaller tummies take less milk.) Breastfed babiesâ milk intake doesnât increase from months 1 to 6 because their growth rate slows.4 As growth slows, breastfed babies continue to get bigger and heavier on about the same daily milk intake, averaging about 25 ounces (750 mL) per 24 hours.
On average a breastfed baby will double their birth weight by the time they are six months old. At 12 months, a breastfed baby will weigh about 2.5 times their birth weight. Exclusively breastfed babies tend to double their birth weight by five months.
