A 5-month-old typically drinks 24 to 30 ounces of breast milk per day, spread across about six to seven feedings. That works out to roughly 3 to 5 ounces per feeding, though the exact amount varies from baby to baby and even from one feeding to the next.
Daily Totals and Per-Feeding Amounts
Between 1 and 6 months of age, most breastfed babies consume 24 to 30 ounces of milk in a 24-hour period. What’s interesting about breast milk intake is that it stays relatively stable during this window. Unlike formula-fed babies, who tend to drink progressively larger volumes as they grow, breastfed babies usually hit their peak daily intake around one month and hold fairly steady from there. The milk itself changes in composition to meet the baby’s evolving nutritional needs, so the volume doesn’t need to climb dramatically.
At five months, most babies eat every 4 to 6 hours during the day, with many still taking one or two overnight feeds. That typically adds up to six or seven nursing sessions. If you’re bottle-feeding expressed milk, aim for 3 to 4 ounces per bottle and offer additional milk if your baby still seems hungry. A 5-month-old’s stomach holds about 6 to 7 ounces, so there’s a natural ceiling on how much they can comfortably take in at once.
Pumped Bottles vs. Nursing at the Breast
If you’re pumping and sending bottles to daycare, the 3-to-4-ounce-per-bottle guideline is a good starting point. Some parents instinctively prepare larger bottles as their baby gets older, but this can lead to overfeeding. Babies tend to drink more from a bottle than they would at the breast because the flow is faster and the sucking reflex keeps them going even after they’re full.
A practical approach: start with 3 to 4 ounces, use a slow-flow nipple, and pause partway through the feeding to give your baby a chance to signal that they’re done. If your baby consistently finishes the bottle and still shows hunger cues (rooting, fussiness, sucking on hands), bump up by half an ounce. If your baby regularly leaves milk behind, scale down. You’ll dial in the right amount within a few days.
What About Starting Solids?
Five months falls in the gray zone for solid foods. The American Academy of Pediatrics recommends exclusive breastfeeding for approximately six months and notes that babies under six months get everything they need from breast milk alone. Introducing solids before four months is linked to increased weight gain and higher body fat in infancy and early childhood.
Some pediatricians give the green light closer to five months if a baby shows readiness signs like sitting with support, reaching for food, and losing the tongue-thrust reflex. If your baby has started tasting small amounts of purees or cereal, those early solids are meant to complement breast milk, not replace it. Offer them after a nursing session, not before, so milk remains the primary source of calories and nutrition. You may notice breastfeeding sessions gradually decrease as solid food intake increases over the coming months, but at five months, the shift is minimal.
How to Tell Your Baby Is Getting Enough
Counting ounces is straightforward when you’re bottle-feeding, but if you’re nursing directly, you can’t measure what goes in. Instead, focus on what comes out and what the scale says.
- Wet diapers: At least six heavy, wet diapers every 24 hours. If you use disposables and aren’t sure what “heavy” feels like, add 2 to 4 tablespoons of water to a dry diaper for comparison.
- Dirty diapers: Stools should be soft and yellowish. The frequency can vary widely at this age. Some breastfed babies go several days between bowel movements, which is normal as long as the stool is soft when it arrives.
- Steady weight gain: A 5-month-old typically gains about 1¼ pounds over the course of the month, or roughly 5 ounces per week. Your pediatrician tracks this on a growth chart, and the trend matters more than any single weigh-in.
- Contentment between feeds: A baby who seems satisfied after nursing, is alert during wake windows, and isn’t constantly fussy is almost certainly getting enough.
When Intake Looks Low or High
Some babies are efficient nursers who drain a breast in seven minutes. Others take 20 minutes per side. Session length is a poor indicator of how much milk a baby actually transfers. A short feed doesn’t automatically mean a small feed.
If your baby is gaining weight along their growth curve and producing plenty of wet diapers, their intake is almost certainly fine, even if it seems like they’re nursing for shorter stretches than they used to. Babies get faster and more skilled at extracting milk as they get older.
On the other end, a baby who wants to nurse constantly or seems unsatisfied after every feeding may be going through a growth spurt, which is common around four to five months. These typically last a few days. Nursing more frequently during a spurt signals your body to increase production, and supply usually catches up within 48 to 72 hours. If the pattern persists beyond a week or your baby’s weight gain stalls, that’s worth bringing up at your next pediatrician visit.
