A 6-month-old typically drinks 24 to 32 ounces of breast milk or formula per day, spread across four to six feedings. That total starts to shift slightly downward as solid foods enter the picture around this age, but milk remains the primary source of calories and nutrition through the first year.
Daily Totals for Formula-Fed Babies
Most 6-month-olds on formula take in somewhere between 24 and 32 ounces in a 24-hour period, usually split into five or six bottles. A typical feeding is 6 to 8 ounces at a time, though some babies prefer smaller, more frequent bottles. The 32-ounce mark is a useful number to remember: babies getting at least that much formula each day don’t need a separate vitamin D supplement, since formula is fortified with it. Babies drinking less than 32 ounces daily do need supplemental vitamin D.
As your baby starts eating solid foods, you may notice they drink slightly less formula at certain feedings. That’s normal. The goal isn’t to hit an exact ounce count every day. It’s to make sure milk stays the foundation of their diet while solids are gradually introduced alongside it.
Daily Totals for Breastfed Babies
Breastfed babies at 6 months typically nurse about four to five times per day once they’re eating solids well. Since you can’t measure ounces at the breast the way you can with a bottle, the best indicators of adequate intake are steady weight gain and consistent wet diapers (at least four to six per day).
Breast milk composition adjusts over time, so even as the number of nursing sessions decreases from the newborn stage, your baby is getting more calorie-dense milk per session. If you’re pumping and bottle-feeding, most 6-month-olds take around 24 to 30 ounces of expressed milk daily, though individual needs vary.
How Solid Foods Fit In
Six months is when most babies begin solid foods, but “begin” is the key word. At this stage, solids are about exposure and practice, not replacing milk. A few tablespoons of pureed vegetables, fruit, or infant cereal once or twice a day is plenty for a baby just starting out. Milk feedings should come first, with solids offered afterward or between nursing or bottle sessions.
Over the next several months, the ratio gradually shifts. But at 6 months, expect milk to still account for the large majority of your baby’s caloric intake. If your baby seems less interested in the breast or bottle after a big serving of solids, scale back the food portions rather than the milk.
What About Water?
Once your baby starts solids at 6 months, you can begin offering small amounts of water. The CDC recommends 4 to 8 ounces per day for babies between 6 and 12 months. That’s just a few sips with meals, not a full bottle. Water at this age is about getting your baby used to the taste and the cup, not about hydration. Breast milk and formula already handle that.
Night Feedings at 6 Months
By 6 months, most babies can sleep six to eight hours at a stretch without needing to eat. Nighttime calories aren’t necessary for healthy growth at this age. Many babies still wake to feed out of habit rather than hunger, and pediatricians at UCSF Benioff Children’s Hospitals note that this is a reasonable time to start gently reducing nighttime feedings if that’s something you’re ready for.
If you’re breastfeeding and want to wean off night feeds gradually, one approach is to nurse from only one side during nighttime wake-ups, which naturally reduces the volume your baby takes in. For bottle-fed babies, some parents offer water instead of formula at night to break the association between waking and a full feeding.
Signs Your Baby Is Getting Enough
Rather than fixating on exact ounces, it helps to watch your baby’s behavior and growth. Between 3 and 6 months, healthy babies gain at least about two-thirds of an ounce per day. Your pediatrician tracks weight at well-child visits, but at home, the day-to-day signals are more practical.
A baby who’s getting enough milk will have regular wet and dirty diapers, seem satisfied after feedings, and stay on a consistent growth curve. Hunger cues at this age include reaching or pointing toward food, opening the mouth when a spoon or bottle approaches, and getting visibly excited at the sight of food. Fullness cues are equally clear: pushing food or the bottle away, closing the mouth, turning the head, or using hand gestures to signal “done.”
These cues are more reliable than any chart. Some 6-month-olds consistently drink 26 ounces a day and thrive. Others need closer to 32. Letting your baby guide the feeding, within the general range, is the most effective approach.
When Intake Seems Too Low or Too High
If your baby is consistently taking less than 20 ounces of formula or nursing fewer than three times a day and their weight gain has slowed, that’s worth bringing up with your pediatrician. Slow weight gain at this age is defined as less than about two-thirds of an ounce per day, according to Boston Children’s Hospital.
On the other end, a baby drinking well over 32 ounces of formula daily may be comfort-feeding or drinking too fast from a bottle with a flow that’s too quick. Paced bottle feeding, where you hold the bottle more horizontally and let the baby take breaks, can help match the slower pace of breastfeeding and give the baby time to register fullness. If your baby seems hungry all the time despite adequate milk intake, it may be a sign they’re ready for more substantial solid foods rather than extra bottles.
