A 5-month-old typically drinks 24 to 32 ounces of breast milk or formula per day, spread across four to six feedings. The exact amount varies by baby, but a reliable rule of thumb is about 2.5 ounces of formula per pound of body weight per day. A 14-pound baby, for example, would need roughly 35 ounces, though most babies cap out around 32 ounces daily.
Formula Feeding at 5 Months
Most formula-fed 5-month-olds eat every three to four hours and take 6 to 8 ounces per bottle across four or five feedings. That typically adds up to somewhere between 24 and 32 ounces in a 24-hour period. The 2.5-ounces-per-pound guideline from the American Academy of Pediatrics gives you a personalized starting point, but your baby’s appetite will fluctuate day to day. Some feedings will be big, others smaller.
There’s a ceiling to keep in mind: babies generally shouldn’t average more than about 32 ounces of formula in 24 hours. Consistently exceeding that can signal the baby is being fed past fullness or that something else (like reflux discomfort) is driving extra sucking. If your baby regularly drains bottles and still seems hungry beyond 32 ounces, that’s often a sign they’re ready for solid foods rather than more formula.
Breastfeeding at 5 Months
Breastfed babies at this age typically nurse 8 to 12 times in 24 hours, though some have started to consolidate feedings and may land closer to 6 or 7 sessions. Because you can’t measure ounces at the breast, the best gauge is your baby’s growth and diaper output. Six or more wet diapers a day and steady weight gain mean your baby is getting enough.
Feeding sessions vary in length throughout the day, and that’s completely normal. A baby might nurse for 20 minutes in the morning and only 5 minutes in the afternoon. Babies self-regulate well at the breast and will generally stop when they’re full.
How to Tell Your Baby Is Full
At 5 months, babies give clear signals when they’ve had enough. They close their mouth, turn their head away from the breast or bottle, and relax their hands. Earlier in a feeding, their fists tend to be clenched and their body tense with focus. When those hands go soft and open, the baby is winding down.
Pushing the bottle or breast on a baby who’s showing these signs can override their natural ability to self-regulate. Letting your baby decide when to stop, even if the bottle isn’t empty, helps them develop healthy eating patterns that carry into childhood.
Night Feedings at 5 Months
Most 5-month-olds still wake to eat at least once during the night, and many wake twice. This is normal. Formula-fed babies can sometimes stretch longer between nighttime feedings and may be ready to phase out night feeds around 6 months. For breastfed babies, nighttime nursing serves both nutritional and comfort purposes, and most experts suggest waiting until closer to 12 months before deliberately weaning night feeds.
If your baby is eating well during the day but still waking frequently at night, the wake-ups may be more about comfort or sleep cycles than hunger. But at 5 months, it’s generally too early to cut night feeds entirely.
Is Your Baby Ready for Solid Foods?
Five months sits right at the edge of when some babies start showing interest in solid food. Most pediatricians recommend starting solids between 4 and 6 months, but the timing depends on your individual baby hitting certain milestones, not just their age on the calendar.
The signs of readiness include: holding their head up steadily without wobbling, sitting upright with some support, having doubled their birth weight (reaching at least about 13 pounds), and showing clear interest in food. That interest often looks like staring at your plate, opening their mouth when they see a spoon approaching, or reaching for food.
If your baby checks those boxes, you can introduce very small amounts of pureed food. Start with just a teaspoon or two, ideally sandwiched between breast milk or formula at the beginning and end of the meal. The goal at this stage isn’t calories or nutrition. Breast milk or formula still provides virtually everything your baby needs. Solids at 5 months are about exposure, texture exploration, and practice with the mechanics of eating from a spoon.
Tracking Healthy Growth
Weight gain is the most reliable indicator that your baby is eating enough. At 5 months, babies typically gain about 20 grams (roughly two-thirds of an ounce) per day. That’s slower than the first few months, when daily gains averaged closer to an ounce. By 6 months, the rate slows further to about 10 grams a day. This natural deceleration is expected and doesn’t mean your baby needs more food.
Your pediatrician tracks your baby’s growth on a percentile chart at each visit. What matters most isn’t the specific percentile but whether your baby is following a consistent curve over time. A baby steadily tracking the 25th percentile is growing just as healthily as one on the 75th. A sudden drop or jump across percentile lines is what warrants a closer look at feeding.
If your baby seems content after feedings, is gaining weight steadily, and produces plenty of wet diapers, they’re almost certainly getting exactly what they need, whether the daily total lands at 24 ounces or 32.
