Baby Feeding Chart: How Many Ounces of Milk by Age (0-12 Months)

These are normal ranges, not requirements: there is no single exact amount that fits every baby. A baby who regularly drinks a bit less or a bit more, while gaining weight normally and staying active between feeds, needs no adjustment. The daily total dips slightly after 6 months because solid food starts supplying some of the energy milk used to provide alone. That’s not a sign your baby is eating worse, it just means their diet is diversifying.

The First Days: Why Newborns Drink So Little

A newborn drinks only about 1/5 to 1/4 ounce (5-7 mL) on day one of life, rising to roughly 3/4 to 1 ounce (22-27 mL) by day 3, and 1.5 to 2 ounces (45-60 mL) by day 7. That’s not an appetite problem: a newborn’s stomach is about the size of a small cherry on day one, growing to about the size of an apricot by day 7. It physically cannot hold much more. Offering large volumes too early, at the breast or the bottle, exceeds a newborn’s actual stomach capacity and tends to trigger spit-up rather than better intake.

Over the first two weeks or so, in what’s often called the newborn stage, whether you’re breastfeeding or preparing a bottle, the priority is feeding on demand rather than chasing a specific ounce count. Appetite can vary from one day to the next, and from one baby to the next, and that’s part of normal growth and development.

What the Science Really Says About Milk Volume

The reference ranges above rest on population data, but recent research sharpens what "real need" actually means at each age.

Milk needs drop in proportion to body weight, not just in absolute terms. A systematic review and meta-analysis covering 167 studies and thousands of infants found that average breast milk intake reaches about 670 mL (roughly 22-23 oz) a day, but the amount per kilogram of body weight declines sharply with age: about 135 mL/kg/day at 1 month, versus just 61 mL/kg/day at 12 months (Rios-Leyvraz & Yao, 2023). In other words, a 10-month-old who seems to "drink less" than at 2 months is often following a completely normal trajectory: their relative milk need has genuinely dropped, not just their appetite.

High formula volumes early on are linked to higher weight later. A cohort study following over 1,000 infants compared breastfed babies, babies on a moderate formula volume, and babies on a high formula volume (28 ounces / 840 mL or more per day) by 3 months. The high-volume group showed significantly higher weight and length, a gap that persisted through 12 months (Huang et al., 2018). This doesn’t mean restricting your baby. It means that a fixed volume imposed on every feed, rather than one guided by hunger and fullness cues, can push intake higher without any real benefit to the baby.

The 6-12 month transition now has clearer international guidance. A 2024 multi-society response, coordinated by WHO and endorsed by ESPGHAN, sets out complementary feeding guidance for infants aged 6-23 months, confirming that milk (breast or formula) remains the main source of nutrients through the first year, even once solids are introduced (WHO/ESPGHAN, 2024). Milk isn’t "replaced" by solid food at 6 months. It stays central, and solids gradually complement it.

Breastfed vs. Formula-Fed: Why the Numbers Differ

Parents often notice that breastfed babies seem to eat "less" per feed than formula-fed babies, and more often. That difference is real and well documented: breast milk is digested faster than formula, so breastfed babies typically nurse more frequently, in smaller amounts, than formula-fed babies who go longer between larger bottles.

This is one reason ounce-based charts work better as a rough guide for formula-fed and pumped-milk feeding than for at-the-breast nursing, where volume simply can’t be measured feed by feed. For a breastfed baby, growth tracked at pediatric visits is a far more reliable signal than any ounce count.

Paced Bottle Feeding: How to Avoid Overfeeding

Paced bottle feeding is a technique designed to slow down bottle feeds so they mimic the natural rhythm of nursing, giving a baby more control over how much they take in. In practice: hold the bottle horizontally rather than tipped up, let the baby actively suck rather than letting gravity do the work, and pause every few minutes to see whether the baby wants to continue.

Research on responsive, cue-based feeding interventions supports this approach as a way to help babies self-regulate intake and reduce the risk of overfeeding, particularly for bottle-fed babies who might otherwise be encouraged to finish every ounce (Bahorski et al., 2023). Paced feeding is especially useful for babies who gulp quickly, spit up often, or seem uncomfortable after bottles.

How to Tell If Baby Got Enough, Without Just Counting Ounces

The ounce count in a bottle or at the breast is only an approximation of good feeding. These signs are more reliable than any number, whatever your baby's feeding schedule looks like:

• The growth curve. Weight and length tracked by your pediatrician at routine visits remain the gold-standard signal for whether overall intake is adequate.
• Wet diapers. From the second week on, 5 to 6 well-wet diapers a day point to good hydration and adequate intake.
• Behavior after a feed. A satisfied baby relaxes, releases the nipple or bottle on their own, and seems calm or drowsy between feeds.
• Active fullness cues. Slower sucking, turning the head away, clamping the mouth shut, or pushing the bottle away are all clear signals that your baby is done, even if milk is left in the bottle.

The rule worth remembering: the amount in a pre-made bottle is never an obligation to finish. Like any human, babies naturally regulate their appetite from one feed to the next.

What Changes After 6 Months, With Solid Foods

Starting solids, generally recommended around 6 months, doesn’t replace milk overnight. In the early weeks, solids are added in small amounts, once or twice a day, without meaningfully cutting into milk feeds.

Gradually, over these 6-12 months, the number of milk feeds drops naturally as solid meals take up more space: three to four feeds around 6-9 months, then two to three around 9-12 months, on top of meals. This gradual shift is sometimes called weaning, though in the US the word is also used loosely for starting solids. The total daily amount of formula or breast milk still matters though, staying around 16-20 ounces (500-600 mL) per the international guidelines above, since milk keeps supplying a meaningful share of calcium, fats, and, for formula, iron.

A practical habit for parents: offer milk before solids in the early weeks after you introduce solid foods, while milk is still the main nutrient source, then gradually flip that order as appetite for solids grows, usually after 9 months, when most babies start handling small pieces of table food. Many babies also continue to breastfeed well past their first birthday as they move into toddlerhood; the WHO/ESPGHAN guidance above treats that as normal, not something to actively wean off of.

A note on cow’s milk. Plain cow’s milk should not replace breast milk or formula as a baby’s main drink before 12 months; its protein and mineral content isn’t suited to a still-maturing digestive system. A little cow’s milk mixed into yogurt or a cooked dish after solids begin is fine. It’s swapping it in as the day’s main milk that should wait until the first birthday.

A note on vitamin D. The American Academy of Pediatrics recommends a daily vitamin D supplement for exclusively or partially breastfed babies, since breast milk alone typically doesn’t provide enough. Formula-fed babies drinking enough infant formula usually get sufficient vitamin D from the formula itself; ask your pediatrician if you’re unsure which applies to your baby.

A note on food allergies. When you introduce a new solid food, especially common allergens like peanut, egg, or dairy, offer it one at a time and wait a couple of days before adding another, so a reaction is easy to trace back to its source. Most babies tolerate new solid foods without issue, but talk to your pediatrician first if there’s a family history of food allergy.

Common Mistakes to Avoid

Forcing baby to finish the bottle. Emptying a pre-measured bottle every time, even when your baby is showing fullness cues, leads to a repeated calorie surplus. This is exactly the mechanism behind the high-volume formula study discussed above.

Waking baby at night to "make up" a missed daytime volume. Past the first few weeks, and barring specific medical advice, a baby who is gaining weight well doesn’t need to be woken to hit a theoretical daily total. If you use an evening feed to stretch the first part of the night, our guide on the dream feed covers how to do it without a full wake-up.

Comparing your baby to a chart down to the ounce. The ranges in this guide cover the large majority of healthy babies, but an isolated gap of half an ounce, or an occasionally skipped feed, almost never signals a problem. What matters is the trend over several days, and the growth curve.

Ignoring early hunger cues. Waiting for full-on crying before offering milk, rather than responding to subtler cues (rooting, hand to mouth, fidgeting), can make the feed harder. Baby arrives already stressed by the time feeding starts.

FAQ

How do I know if my baby is drinking enough milk?

The most reliable sign isn’t the ounces in the bottle but your baby’s growth curve, tracked by your pediatrician at routine visits. Day to day, 5 to 6 wet diapers a day, steady weight gain, and a baby who relaxes after feeds are good signs of an adequate intake. This chart gives reference ranges, not targets to force.

Should I wake my baby at night to finish a bottle?

No, unless your pediatrician advises otherwise (low birth weight, prematurity, poor weight gain). Past the first few weeks, a baby who is gaining weight well and sleeping longer stretches on their own doesn’t need to be woken to hit a theoretical daily total. Sleep and appetite tend to regulate together; forcing a wake-up for a fixed volume works against your baby’s natural cues.

How much milk should my baby drink after starting solids at 6 months?

Breast milk or formula stays the main source of nutrition through 12 months, even after solids are introduced. International guidelines put intake around 16-20 ounces (roughly 500-600 mL) per day once solids are well established, spread across 3 to 4 feeds, with solids gradually complementing rather than replacing milk.

My baby is refusing the bottle or eating less than usual, should I worry?

A temporary dip in appetite is common during teething, a cold, or a rough sleep stretch, and usually resolves within a few days. Signs that warrant a prompt pediatric check: refusal lasting more than 24-48 hours, weight loss, lethargy, or fewer than 4 wet diapers a day.

Can a baby drink too much milk?

Yes. A study following over 1,000 infants found that formula intake above roughly 28 ounces (840 mL) a day at 3 months was linked to higher weight through the first year. Following your baby’s fullness cues, turning away, slowing down, clamping the mouth shut, rather than a fixed volume is the best protection against overfeeding.

Key Takeaways

• Milk amounts by age shift fast: from 1-2 oz per feed at birth to 6-8 oz by the first birthday, with the number of feeds dropping as volume rises.
• Real need drops in proportion to body weight, not just in absolute ounces: a bigger baby drinking a stable volume is often right on track.
• After 6 months, milk stays the main nutrient source even with solids, at roughly 16-20 ounces (500-600 mL) a day.
• Fullness cues (turning away, slower sucking, mouth closing) are more reliable than any ounce target.
• A consistently high formula volume is linked to higher weight by age one: following your baby beats following the chart.
• Paced bottle feeding helps bottle-fed babies self-regulate intake closer to how nursing naturally works.
