A 6-month-old typically drinks 6 to 8 ounces of breast milk or formula per feeding, with 4 or 5 feedings spread across 24 hours. That puts the daily total somewhere around 24 to 32 ounces for most babies. The exact amount varies depending on your baby’s size, appetite, and whether they’ve started eating solid foods.
Per Feeding and Daily Totals
At 6 months, most babies have settled into a predictable rhythm of fewer but larger feedings compared to their newborn days. The American Academy of Pediatrics’ HealthyChildren.org guidelines put each feeding at 6 to 8 ounces, happening 4 or 5 times a day. So a baby on the lower end might drink about 24 ounces total, while a hungrier baby could take in closer to 40 ounces, though most fall in the 24 to 32 ounce range.
Feedings are generally spaced about every 3 to 4 hours during waking hours, with some babies still taking one feeding overnight. Breastfed babies may feed slightly more often because breast milk digests faster than formula, but the total daily volume tends to be similar.
How Solid Foods Change the Picture
Six months is when most babies start complementary foods like pureed fruits, vegetables, and infant cereal. This is the beginning of a gradual shift. At first, solid foods are more about practice than nutrition, so breast milk or formula still provides the bulk of your baby’s calories and nutrients.
As your baby gets better at eating solids over the coming weeks and months, their milk intake will naturally decrease. This is normal and expected as long as your baby is growing well. A good rule of thumb: offer breast milk or formula before solids at this age, so your baby fills up on milk first and treats food as a supplement rather than a replacement. By the time babies approach their first birthday, the balance flips and solid foods become the primary source of nutrition.
Breastfed vs. Formula-Fed Babies
If you’re breastfeeding directly, you obviously can’t measure ounces coming from the breast. That’s completely fine. Breastfed babies self-regulate their intake, and feeding on demand remains the best approach at 6 months. As babies get older, they often become more efficient at the breast, finishing feedings faster even though they’re getting plenty of milk. A feeding that took 20 minutes at 2 months might take 10 minutes now.
If you’re pumping and bottle-feeding breast milk, 24 to 32 ounces per day is a reasonable target. Formula-fed babies tend to land in that same range. Babies who are larger or going through a growth spurt may temporarily want more, and that’s normal too.
Signs Your Baby Is Getting Enough
Rather than fixating on an exact ounce count, watch your baby for reliable signs of adequate intake. Steady weight gain along their growth curve is the single best indicator. Your pediatrician tracks this at well-child visits, and consistent growth means your baby is getting what they need regardless of whether the daily total hits a specific number.
Day to day, look for 6 or more wet diapers in 24 hours. A well-fed baby is generally alert and active during awake periods, meeting developmental milestones, and seems satisfied after feedings rather than fussy and rooting for more. If you’re breastfeeding, your breasts should feel noticeably softer after a feeding. You can also watch your baby’s chin during nursing: a rhythmic suck followed by a visible pause where the jaw drops means your baby is swallowing a mouthful of milk.
When Intake Seems Too Low or Too High
Some babies are naturally smaller eaters who hover around 24 ounces, while others consistently want 32 or more. Both can be perfectly healthy. The concern isn’t a single day of low intake (teething, a mild cold, or a distracted baby can all cause temporary dips) but a pattern of consistently drinking much less than usual combined with poor weight gain or fewer wet diapers.
On the upper end, formula-fed babies who regularly exceed 32 ounces per day and seem unsatisfied may be ready for more solid foods or may be using the bottle for comfort rather than hunger. Offering a pacifier between feedings or checking whether boredom rather than hunger is driving the demand can help. Breastfed babies rarely overfeed because the breast requires active effort to get milk, which naturally regulates intake.
What About Water and Juice?
At 6 months, you can introduce small sips of water, especially once your baby starts solids. There’s no need to push it, though. Breast milk and formula already provide all the hydration your baby needs. If you choose to offer juice, the AAP recommends limiting it to 4 to 6 ounces per day and waiting until at least 6 months. Whole fruit is a better option nutritionally since juice is essentially sugar water without the fiber.
