A 5-month-old typically drinks 24 to 32 ounces of formula or breast milk per day, spread across four to six feedings. The exact amount depends on your baby’s weight, whether they’re breastfed or formula-fed, and their individual appetite on any given day.
Daily Totals for Formula-Fed Babies
The American Academy of Pediatrics recommends about 2½ ounces of formula per day for every pound of body weight. An average 5-month-old weighs around 14 to 16 pounds, which puts the daily total somewhere between 25 and 32 ounces. The upper limit is 32 ounces in 24 hours. Going consistently above that threshold isn’t necessary and can contribute to overfeeding patterns.
At this age, most formula-fed babies take 5 to 7 ounces per bottle across four to five feedings a day. Some babies prefer smaller, more frequent bottles, while others drink larger amounts less often. Both patterns are normal as long as the daily total falls in the expected range and your baby is gaining weight steadily.
Daily Totals for Breastfed Babies
Breastfed 5-month-olds typically consume 24 to 30 ounces of breast milk in 24 hours. If you’re pumping and bottle-feeding expressed milk, individual bottles usually hold 3 to 4 ounces, offered more frequently than formula since breast milk digests faster.
If you’re nursing directly, you won’t know exact ounce counts, and that’s fine. The best indicators that your baby is getting enough are consistent weight gain, six or more wet diapers a day, and a baby who seems satisfied after feedings.
How to Calculate Your Baby’s Needs
The 2½-ounce-per-pound guideline gives you a personalized starting point. Weigh your baby (or use the number from their last checkup), then multiply by 2.5. A 15-pound baby, for example, needs roughly 37.5 ounces by this formula, but since the daily cap is 32 ounces, you’d aim for that upper limit instead. Babies naturally regulate their intake from day to day, so treat these numbers as a general target rather than a strict rule.
Reading Your Baby’s Hunger and Fullness Cues
Your baby will tell you when they’re hungry and when they’ve had enough, even though they can’t use words yet. Hunger cues at this age include putting hands to the mouth, turning toward the breast or bottle, and smacking or licking lips. Clenched fists are another early signal. Crying is actually a late hunger cue, so try to catch the earlier signs before your baby gets upset.
When your baby is full, they’ll close their mouth, turn their head away from the bottle or breast, and relax their hands. Pushing the nipple out with their tongue or losing interest mid-feed are also clear signals. Following these cues rather than trying to get your baby to finish a set number of ounces is the best way to prevent both underfeeding and overfeeding.
Growth Spurts and Temporary Increases
Around 4 to 6 months, many babies go through a growth spurt that temporarily increases their appetite. During these stretches, your baby may want to eat more frequently, sometimes as often as every one to two hours, and may seem unsatisfied with their usual bottle size. Growth spurts typically last only a few days. Once the spurt passes, feeding patterns usually return to normal.
If your baby’s appetite increases and stays elevated for more than a week, it likely reflects their growing size rather than a temporary spurt. Adjusting their daily total upward, while staying at or below 32 ounces, is appropriate.
Night Feedings at 5 Months
By 5 months, many babies can sleep five or more hours at a stretch without eating. One or two nighttime feedings is still common and normal at this age, but if your baby is waking to eat more than twice per night, it may be a habit rather than a nutritional need. Gradually spacing out night feedings can help your baby (and you) get longer stretches of sleep while shifting more of their calorie intake to daytime hours.
What About Solid Foods?
Five months is right on the edge of when some babies start showing interest in solid food. The AAP and the Dietary Guidelines for Americans recommend introducing solids at about 6 months, though not before 4 months. At 5 months, your baby may be ready if they can sit up with support, hold their head steady, open their mouth when offered food, and swallow rather than push food back out with their tongue.
If you do start offering small tastes of pureed food at 5 months, breast milk or formula should still provide the vast majority of your baby’s calories and nutrition. Solids at this stage are about exploration and practice, not replacing milk feedings. Don’t reduce bottle or nursing volume to make room for solids yet.
