Most 4-month-olds eat every 3 to 5 hours, which works out to about 5 to 8 feedings in a 24-hour period. The exact number depends on whether your baby is breastfed, formula-fed, or getting a combination of both. At this age, your baby’s stomach is bigger than it was in the newborn days, so feedings are more spaced out and more predictable.
Breastfeeding at 4 Months
Breastfed babies typically nurse 8 to 12 times in 24 hours, though by 4 months many settle closer to the lower end of that range. Some feeding sessions will be long and others surprisingly short. That’s normal. Babies regulate their own intake at the breast and stop when they’re full, so the length of a session isn’t a reliable measure of how much milk they’re getting.
You may also notice your baby nursing more frequently for a day or two, then spacing out again. These “cluster feeding” spurts often line up with growth spurts and help signal your body to increase milk production. They’re temporary and don’t mean your supply is dropping.
Formula Feeding at 4 Months
Formula-fed 4-month-olds generally eat every 3 to 4 hours. Most babies this age take somewhere between 4 and 6 ounces per feeding, with a typical daily total around 24 to 32 ounces. If your baby consistently takes more than 32 ounces a day, it’s worth mentioning at your next pediatrician visit, since overfeeding with formula is easier than with breastfeeding.
One useful benchmark: babies who receive about 32 ounces or more of formula daily are getting enough vitamin D from the formula itself and don’t need a separate supplement.
What About Night Feedings?
By 4 months, many babies can stretch 5 or more hours between feedings at night. That means one or two night feeds is common and completely normal. If your baby is waking to eat more than twice per night at this age, it may be worth exploring whether they’re truly hungry or have developed a habit of waking for comfort.
Some 4-month-olds drop to a single night feed on their own. Others aren’t ready for that yet, especially breastfed babies, since breast milk digests faster than formula. There’s no single “right” age to eliminate night feeds entirely. The trend you’re looking for is a gradual decrease over weeks, not an abrupt change.
How to Tell Your Baby Is Getting Enough
Diaper output is the simplest daily check. After the first week of life, a well-fed baby produces at least 6 wet diapers per day. The number of dirty diapers varies more, especially in breastfed babies, where anything from several per day to one every few days can be normal at this age.
Weight gain is the most reliable longer-term sign. At 4 months, babies typically gain about 1 to 1.25 pounds per month. Most have doubled their birth weight by 4 to 5 months. Your pediatrician tracks this on a growth chart at each well visit, so you don’t need to weigh your baby at home unless you’ve been asked to.
Reading Your Baby’s Hunger Cues
At 4 months, your baby communicates hunger and fullness with clear physical signals. Feeding on cue, rather than on a rigid clock-based schedule, helps your baby eat the right amount for their body.
Signs your baby is hungry:
- Putting hands to their mouth
- Turning their head toward your breast or the bottle (rooting)
- Smacking, puckering, or licking their lips
- Clenching their fists
Signs your baby is full:
- Closing their mouth
- Turning their head away from the breast or bottle
- Relaxing their hands
Crying is actually a late hunger signal. If your baby is crying from hunger, they may be too upset to latch or eat well right away. Catching the earlier, quieter cues makes feedings smoother for both of you.
Should You Start Solids Yet?
Four months is the earliest age at which solids are considered safe, but both the American Academy of Pediatrics and the Dietary Guidelines for Americans recommend waiting until about 6 months. Introducing foods before 4 months is not recommended under any guidelines.
If you’re considering starting between 4 and 6 months, look for these developmental readiness signs: your baby can sit up with support, has good head and neck control, opens their mouth when offered food, swallows food instead of pushing it out with their tongue, brings objects to their mouth, and tries to grasp small items. Most 4-month-olds haven’t hit all of these milestones yet. Either way, breast milk or formula remains the primary source of nutrition through the entire first year, even after solids are introduced.
