A 5-month-old typically drinks 24 to 32 ounces of formula per day, spread across four to six feedings. Breastfed babies at this age nurse about eight to twelve times in 24 hours, taking what they need at each session. At 5 months, breast milk or formula is still your baby’s sole source of nutrition, and the exact amount varies from one baby to the next.
Daily Formula Amounts
Most 5-month-olds take between 6 and 8 ounces per bottle, with four to five bottles throughout the day. The American Academy of Pediatrics recommends that babies drink no more than an average of about 32 ounces of formula in 24 hours. Babies who consistently hit that 32-ounce mark don’t need a separate vitamin D supplement, since formula is already fortified.
Not every feeding will look the same. Some bottles your baby will drain, and others they’ll barely touch. That’s normal. Babies generally take what they need at each feeding and stop when they’re full. Trying to get your baby to finish every last ounce can lead to overfeeding and discomfort, so it’s better to follow their lead.
How Breastfeeding Looks at 5 Months
Measuring ounces is harder when you’re breastfeeding, which is why frequency and feeding cues matter more than volume. On average, exclusively breastfed babies feed every 2 to 4 hours, totaling about 8 to 12 sessions per day. Some of those sessions will be quick comfort feeds, others will be long and leisurely. Both count.
By 5 months, many breastfed babies have become more efficient at the breast, finishing a feeding faster than they did as newborns. A shorter feed doesn’t necessarily mean your baby got less milk. The better gauge is what’s happening between feedings: steady weight gain, enough wet diapers, and a baby who seems satisfied after eating.
Recognizing Hunger and Fullness Cues
Rather than watching the clock or counting ounces, the most reliable way to know if your 5-month-old is getting enough is to read their signals. Hunger cues at this age include putting hands to the mouth, turning their head toward your breast or bottle, and puckering, smacking, or licking their lips. Clenched fists are another early sign.
Crying is actually a late hunger signal. By the time your baby is wailing, they’ve been hungry for a while and may be too upset to latch or take a bottle easily. Catching those earlier, calmer cues makes feedings smoother for both of you.
Fullness looks like the opposite: your baby closes their mouth, turns their head away from the breast or bottle, and relaxes their hands. These signals mean the feeding is done, even if there’s formula left in the bottle or you expected a longer nursing session.
Night Feedings at 5 Months
By 4 months, many babies can stretch 5 or more hours between feedings overnight. At 5 months, one or two night feedings is typical. If your baby is waking to eat more than twice a night, it may be worth evaluating whether those wake-ups are driven by hunger or by habit.
Some babies genuinely need that overnight nutrition, especially during growth spurts. Others have simply associated waking with feeding and will eat because the bottle or breast is offered, not because they’re truly hungry. Steady daytime intake often helps reduce nighttime feeds naturally over the coming weeks.
How to Tell Your Baby Is Getting Enough
The best evidence that your 5-month-old is well-fed isn’t a specific ounce count. It’s a combination of signs. After the first week of life, babies should produce at least six wet diapers per day. Fewer than that can signal dehydration or insufficient intake.
Weight gain is the other key marker. Between 4 and 6 months, babies typically gain about 1 to 1¼ pounds per month. Most babies have doubled their birth weight by 4 to 5 months. Your pediatrician tracks this on a growth chart, and a consistent curve matters more than hitting an exact number. A baby who’s been in the 25th percentile since birth and stays there is thriving, even if they eat less than a baby tracking along the 75th.
Solids Are Not on the Menu Yet
At 5 months, your baby’s diet should still be exclusively breast milk, formula, or a combination of both. Both the American Academy of Pediatrics and the Dietary Guidelines for Americans recommend introducing solid foods at about 6 months. Starting solids before 4 months is not recommended, and most 5-month-olds aren’t developmentally ready.
Readiness signs to watch for in the coming weeks include sitting up with support, having good head and neck control, opening the mouth when food is offered, and swallowing food rather than pushing it back out with the tongue. Your baby should also be reaching for objects and bringing them to their mouth. Until most of these milestones are in place, breast milk or formula provides everything your baby needs nutritionally.
If your baby seems hungrier than usual at 5 months, the answer is more milk, not early solids. Growth spurts are common at this age and typically last a few days. Offering extra feedings during a spurt helps your baby (and, if you’re breastfeeding, helps your supply adjust to the increased demand).
