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 shifts gradually downward as solid foods enter the picture, but milk remains the primary source of nutrition at this age.
Formula-Fed Babies: Daily Amounts
Formula-fed 6-month-olds generally take 6 to 8 ounces per bottle, four or five times in a 24-hour period. That works out to roughly 24 to 40 ounces total, though most babies land somewhere in the 28 to 32 ounce range. A baby’s stomach at this age holds about 7 to 8 ounces, which is why individual feedings naturally cap out around that size.
You don’t need to push your baby to finish every bottle. Some feedings will be bigger, others smaller. Babies are generally good at regulating their own intake, taking what they need and stopping when they’re full.
Breastfed Babies: What to Expect
Breastfed babies are harder to measure in ounces because you can’t see what’s going in. Most breastfed 6-month-olds nurse five or six times per day, and research suggests they consume roughly 24 to 30 ounces of breast milk in total. The composition of breast milk changes throughout the day and even within a single feeding, so volume alone doesn’t tell the whole story.
If your baby is gaining weight steadily and producing six to eight wet diapers per day, they’re almost certainly getting enough. That diaper count is one of the most reliable indicators of adequate hydration at this age.
How Solid Foods Change the Equation
Six months is when most babies start solid foods, and parents often wonder whether that means less milk. At first, the answer is barely. Early solids are more about exploring tastes and textures than replacing calories. A few spoonfuls of pureed sweet potato or mashed banana don’t provide much energy compared to a full bottle or nursing session.
The general approach is to offer milk first, then solids, so your baby fills up on the nutrition they need most. Over the next several months, the balance gradually shifts as your baby eats larger portions of solid food and naturally drinks a bit less milk at each feeding. But at 6 months specifically, milk still accounts for the vast majority of your baby’s calories and nutrition. Think of solids as a supplement, not a replacement.
Feeding Frequency and Scheduling
Most 6-month-olds eat or drink something every two to three hours during the day, which typically adds up to five or six feeding opportunities. Some parents find a loose schedule helpful: a bottle or nursing session after waking, mid-morning, early afternoon, late afternoon, and before bed, with one or two small solid food “meals” worked in between.
Night feedings are still common. In a study of over 700 mothers with babies ages 6 to 12 months, nearly 79% reported their baby still woke at least once during the night, and about 61% of those babies received at least one milk feeding overnight. So if your 6-month-old is still waking for a feeding at 2 a.m., that’s well within the range of normal.
Signs Your Baby Is Getting Enough
Rather than fixating on exact ounces, watch your baby’s behavior. A hungry 6-month-old will reach for food, open their mouth eagerly when offered a spoon, and get visibly excited at the sight of a bottle or breast. A full baby does the opposite: pushing food away, turning their head, closing their mouth, or fussing when you try to offer more.
These cues are more useful than any chart because every baby is different. A larger baby may consistently drink 8-ounce bottles while a smaller one thrives on 5 or 6 ounces per feeding. Steady weight gain along their own growth curve, six to eight wet diapers daily, and a generally alert, active baby are the signs that matter most.
When Intake Seems Too High or Too Low
If your formula-fed baby is consistently drinking more than 32 ounces per day and seems unsatisfied, it may be a sign they’re ready for more substantial solid foods or that they’re eating for comfort rather than hunger. On the other end, a baby who consistently takes less than 20 ounces and seems sluggish, produces fewer than six wet diapers, or isn’t gaining weight may not be getting enough.
Breastfed babies who suddenly want to nurse constantly for a few days are often going through a growth spurt rather than experiencing a supply problem. These bursts of increased feeding typically last two to three days and help signal your body to produce more milk. Short-term changes in feeding patterns are normal. It’s the longer trends, tracked over weeks, that paint the real picture of whether your baby’s intake is on track.
