How many Oz does a 5-month-old drink a day?

The amount of milk or formula a 5-month-old baby drinks per day can vary quite a bit from baby to baby. However, there are some general guidelines for how much a baby this age typically consumes. In the first few paragraphs, I’ll provide a quick overview of the key points, then dive into more details throughout the article.

Quick Answers

– The average 5-month-old drinks 25-35 oz of milk/formula per day.

– Breastfed babies may drink 25-30 oz per day.

– Formula fed babies may drink 30-35 oz per day.

– Babies will take in more milk as solids are introduced around 6 months.

– Watch for signs of hunger/fullness rather than focusing on exact amounts.

Average Milk Intake

Most 5-month-old babies will drink somewhere between 25-35 oz of milk or formula in a 24 hour period. However, there can be quite a bit of variability from one baby to another based on factors like:

  • Size – Larger babies may drink more than smaller babies.
  • Activity Level – More active babies burn more calories and may need more milk.
  • Solids Intake – Babies eating more solids may drink less milk.
  • Growth Spurts – Periods of rapid growth increase calorie needs.

The best way to determine if your 5-month-old is getting enough milk is to pay attention to hunger/fullness cues, diaper output, and weight gain rather than focusing on hitting an exact daily volume. If your pediatrician is happy with your baby’s growth and development, then you can be assured they are getting sufficient nutrition.

Breastfed Babies

For breastfed 5-month-olds, the normal range of milk consumption is typically around 25-30 oz per day. However, keep in mind that measuring breastmilk intake is not an exact science. The volume a breastfed baby takes in depends on factors like:

  • Mom’s milk supply – Some mothers produce more milk than others
  • Baby’s feeding efficiency – Some babies are more effective at removing milk from the breast
  • Frequency of feedings – Babies who breastfeed more often may take in more total milk

The best way to estimate breastmilk intake is by doing a weighted feed, where you weigh your baby before and after nursing to determine the amount of milk transferred. However, for most breastfeeding mothers, as long as your baby seems satisfied after feeding and is developing well, there is no need to measure exact quantities.

Formula Fed Babies

For formula fed 5-month-olds, milk intake is generally in the range of 30-35 oz per day. However, this can vary based on your baby’s individual needs. Formula fed babies often take in slightly more milk per day than breastfed babies for a few reasons:

  • Formula is less bioavailable than breastmilk, so more ounces are needed to meet nutrient needs.
  • Formula fed babies may be fed on a stricter schedule vs on demand.
  • Overfeeding with bottles is more common than overfeeding at the breast.

When formula feeding a 5-month-old, aim for about 30-35 oz per day. But again, your baby’s pediatrician can best advise you on appropriate intake based on your child’s growth charts and development.

Milk Intake with Solids

Around 6 months of age, most babies will start transitioning from milk/formula alone to eating solid foods in addition to milk feeds. As solids are introduced and increased, the volume of milk intake typically starts to decrease. This is normal, as your child begins getting nutrition from a variety of complementary foods.

Here’s a rough guideline for milk intake as solids are introduced between 6-12 months:

Age Milk Intake
0-6 months 25-35 oz milk/formula only
6-8 months 24-32 oz milk/formula plus solids
9-12 months 16-24 oz milk/formula plus increased solids

As you can see from the table, milk intake starts decreasing as solid food intake increases. But keep in mind that every baby is different, so your pediatrician can best advise you on appropriate milk/solid feeding as you introduce new foods.

Signs Your 5-Month-Old Is Eating Enough

Rather than obsessing over exact daily quantities, the best way to know if your 5-month-old is eating enough is to watch for signs that their nutritional needs are being met. Here are some signs your baby is getting sufficient milk and calories:

  • Steady weight gain and growth – “Following the curve” on growth charts
  • Producing 6-8 wet diapers and regular bowel movements daily
  • Reaching developmental milestones appropriately
  • Seems satisfied and content after eating
  • Good energy levels when awake
  • Sleeping well between feeds

If you are concerned your baby is not eating enough or seems hungrier than usual, contact your pediatrician. They can help determine if there is an issue like slow weight gain or another medical problem.

Signs Your 5-Month-Old Is Eating Too Much

While underfeeding is dangerous for infants, overfeeding can also lead to issues for babies. Here are some signs that your 5-month-old may be getting too much milk or formula:

  • Consistently spitting up large amounts
  • Excessive drooling or milk leaking from mouth
  • Frequent spit ups or wet burps during/after feeds
  • Gassiness or stomach discomfort
  • Feeding more than 36 oz formula daily

If your baby is showing signs of overfeeding, try burping more frequently during feeds or offering smaller volumes per feeding. Consulting your pediatrician can also help determine if your baby needs less milk intake.

Tips for Feeding a 5-Month-Old

Here are some top tips for feeding your 5-month-old to help ensure they are eating the right amount:

  • Offer smaller, more frequent feeds – At this age 4-6 oz per feeding is appropriate.
  • Let your baby show signs of fullness – Don’t force them to finish a bottle.
  • Try paced bottle feeding – Helps prevent overeating.
  • Include awake time – Don’t let baby fall asleep too quickly while feeding.
  • Introduce solid foods – Discuss starting solids with your pediatrician.
  • Watch your baby’s cues – Hunger vs fullness signs.

Following your baby’s hunger/fullness signals is key to ensuring proper nutrition at this age. Their intake may vary from day to day and meal to meal based on factors like growth spurts, activity level, and appetite. Stay in touch with their doctor and address any concerns quickly.

When to Talk to a Doctor

While slight fluctuations in your 5-month-old’s milk intake are normal, you should consult your pediatrician if you notice any of the following:

  • Significant decrease in daily feeding amount
  • Difficulty settling after feeds or increased night wakings
  • Lack of interest in feeding or refusal to eat
  • Few wet diapers or dirty diapers per day
  • Not gaining weight or dropping percentiles on growth chart

These could indicate an illness, allergy, or other issue that needs medical attention. Your pediatrician can help assess whether your child is getting adequate nutrition for healthy growth and development.


The typical 5-month-old drinks 25-35 oz of breastmilk or formula per day. However, each baby’s needs are unique so it’s more important to watch your child’s hunger/fullness cues than to focus on hitting an exact amount. With responsive, paced feeding and introduction of solids around 6 months, your baby should continue to grow and thrive during this time. Don’t hesitate to consult your pediatrician if you have any concerns about your 5-month-old’s feeding patterns or nutrition needs.
