# How Much Formula Does a 5–6 Month Old Drink?

Straight answer: between 5 and 6 months, babies drink a total of **800 to 1,000 ml of formula in 24 hours** (usual AAP cap: ~960 ml), in **4 to 6 feeds**, which works out to **150 to 240 ml per feed, depending on weight and age** (the AAP describes 180 to 240 ml in 4 to 5 feeds at 6 months). This is peak bottle: in most babies the daily volume stops climbing here, and with the start of solids around 6 months it tends to begin, slowly, to come down (at each baby's own pace).

This guide closes our formula-by-age series ([1 month](/en/blog/how-much-formula-1-month-old/) · [2 months](/en/blog/how-much-formula-2-month-old/) · [3 and 4 months](/en/blog/how-much-formula-3-4-month-old/) · [full chart](/en/blog/how-much-formula-by-age/)): what volume to expect, the practical cap few people mention, the night feed that starts to fade, and how to recognize that your baby is ready for the next phase, real food.

> **First things first:** the ranges are for **full-term, healthy** babies. Preemies and babies with any health condition follow the pediatrician's plan. And, as always: these are starting estimates, not targets.

## Chart: volume at 5 and 6 months

| Reference | Typical range |
|---|---|
| **Per feed** | 150 to 240 ml (AAP at 6 months: 180 to 240 ml) |
| **Feeds per 24h** | 4 to 6 (every 3.5–4.5 hours) |
| **Total per day** | 800 to 1,000 ml |
| **Practical cap (AAP)** | ~960 ml/day (32 oz) |

(The ends of the chart don't combine: a baby on 4 feeds takes bigger ones, near 200–240 ml; a baby on 6 takes smaller ones. Nobody adds up 6 feeds of 240 ml.)

Two shifts mark this phase:

- **Fewer feeds, more volume each time.** The stomach holds more and the interval stretches: many babies settle into 5 "full" feeds (morning, mid-morning, afternoon, late afternoon, before bed).
- **The total barely climbs anymore.** From 3 to 6 months the volume curve plateaus: the baby grows, but metabolism per kilo drops and efficiency improves. If you compare with the [3-and-4-months guide](/en/blog/how-much-formula-3-4-month-old/), the range rose only a little, and that's expected.

The by-weight math (~150 ml/kg/day) **loses validity in this phase**: a 7.5 kg baby would get 1,125 ml by the calculator's formula, but in real life almost no baby needs that much. For bigger babies, the practical cap matters more than the per-kilo math: **most stay between 850 and 1,000 ml/day**, and the AAP cites ~960 ml as the usual maximum. Consistently drinking more than that is something to bring to the pediatrician. Sometimes it's real hunger in a big baby, sometimes it's comfort sucking.

## The night starts to empty out

Between 5 and 6 months, many healthy babies with good daytime intake **can go through the night without a feed, nutritionally speaking**. That depends on each baby's growth and health, not just age. In practice it shows up as a night feed that keeps shrinking: the baby wakes, drinks little and without much effort, and is asleep again in minutes. That suggests comfort more than hunger, but no single sign settles it: the pediatrician confirms, looking at growth and health.

Mind the nuances:

- **It's not a goal.** Some babies this age still need 1 overnight feed: especially those born smaller, those in a growth spurt, and those who eat less during the day (the famous "night compensation" of babies too distracted at daytime feeds).
- **Don't cut it on your own.** If the night feed bothers you, go through the pediatrician: often redistributing daytime volume (fuller feeds in the late afternoon) solves it by itself.
- **Waking isn't hunger.** At this age babies have sleep cycles with normal brief wakings; not every waking calls for a bottle. If the baby settles back with presence and comfort, it was a cycle, not hunger.

## Distracted feeds: still here (and slightly worse)

The distraction phase that started at 4 months carries on: the world is too interesting to stop and eat. The baby drinks for 5 minutes, lets go, looks around, comes back, lets go again. Strategies that work:

- Feeds in a **calm environment**: less light, fewer people, less TV.
- **The calm feeds of early morning and the end of the day tend to yield more.** Make use of those quiet times, without forcing. Just don't turn it into feeding a sleeping baby: feeding a baby who's already out overrides fullness cues, reinforces the bottle-sleep association and, with the first teeth coming, favors cavities.
- **Don't chase the baby with the bottle.** If the feed became a fight, pause and try again later. Pushing volume is the shortest path to overfeeding and to aversion.

And the usual ruler for knowing all is well despite the chaos: **wet diapers (6+ a day), weight gain on the curve, and normal energy**. With those three in place, and growth confirmed at checkups, the baby who "barely eats" is eating what they need.

## At 6 months: solids arrive (and what changes with formula)

The WHO and Brazil's Ministry of Health recommend exclusive breastfeeding until 6 months; for formula-fed babies, the Ministry's dietary guide sets the same milestone: **new foods from 6 months**, not before. Three things every parent of a 5-month-old should know first:

1. **Age alone isn't enough — look for the readiness signs:** sitting with support while holding head and trunk steady (a criterion of the SBP, the Brazilian Society of Pediatrics); active interest in food (following your fork with their eyes, opening the mouth, reaching); loss of the tongue-thrust reflex (the one that pushes everything out) and the coordination to bring objects to the mouth. These tend to line up close to 6 months; confirm at the checkup.
2. **In the first weeks, food is more practice than replacement**, but it's not decoration: from 6 months on, foods start covering real needs that milk alone no longer meets (iron and zinc, mainly). Milk remains the calorie base until close to 12 months. Don't cut feeds "to make room": the drop in milk happens on its own, slowly, as meals get going.
3. **What NOT to do before 6 months:** purees, juice (the AAP doesn't recommend fruit *juice* at any point in the first year; fruit itself, mashed or in safe pieces, belongs in starting solids as usual), routine water (correctly prepared formula already hydrates; water comes in with solids, at 6 months, unless medically advised) and thickening the bottle or changing the dilution on your own (the ratio is always the label's; any change is a pediatrician's prescription). None of it improves sleep or "keeps baby fuller", and it crowds out the food your baby actually needs now. The protocol exception between 4 and 6 months exists for specific cases and is the pediatrician's call, never your own.

Two more changes arrive with the full 6 months: **water joins the routine** (in a cup, small sips with solid meals) and many formulas **switch stages** (from first-stage to follow-on); whether, when and to which one is decided at the checkup with the pediatrician, who also assesses your baby's individual nutrient needs there. When solids begin, our [baby-led weaning vs purees guide](/en/blog/blw-vs-purees-6-months/) helps you choose a path.

> **Call the pediatrician without waiting for the routine visit** if: an abrupt, sustained drop in intake with fewer wet diapers, several refused feeds with listlessness, weight gain leaving the curve (down or up), frequent forceful vomiting, or signs of allergy at the bottle (hives, swelling, blood in stools). Persistent doubt about amounts? Bring the feeding log to the visit; it settles the conversation in 2 minutes.

## The log that sets up the next phase

From 5 to 6 months, the follow-up question changes: from "how many ml does he drink?" to "how do we split milk and food?". Arriving at the 6-month checkup with the feeding history (times, volumes, night feed yes/no) is what the pediatrician needs to personalize the solids plan instead of prescribing the generic one.

## FAQ

### How many ml of formula does a 5-month-old drink?

On average, 150 to 240 ml per feed, in 4 to 6 feeds across 24 hours: a total of 800 to 1,000 ml a day, depending on weight and appetite (the AAP cites ~960 ml, 32 ounces, as the usual maximum). What confirms the amount is right isn't the number on the bottle: it's weight gain on the growth curve, wet diapers, and a baby who is active and content between feeds.

### How many ml of formula does a 6-month-old drink?

The same range as at 5 months — 150 to 240 ml per feed, 800 to 1,000 ml a day — with one new thing: solids start at 6 months, and in the first weeks food is practice, not replacement. Milk remains the main calorie source until close to 12 months; the formula total only decreases gradually, as solid meals truly get going.

### Is there a maximum amount of formula per day?

As a practical reference, yes: the American Academy of Pediatrics cites about 960 ml (32 ounces) in 24 hours as the usual cap for exclusively formula-fed babies. Some big babies go slightly past it on growth-spurt days without any problem, but consistently exceeding the cap deserves a conversation with the pediatrician — sometimes it's real hunger, sometimes it's comfort sucking that can be met in other ways.

### My 5-month-old still feeds at night. Hunger or habit?

It can be both. At this age many babies can go through the night without a feed from a nutritional standpoint — but that's neither a rule nor a goal: some still need 1 night feed, especially smaller babies or those in a growth spurt. The sign it's more habit than hunger: the baby drinks little, without much effort, and is back asleep in minutes. For any change to the night routine, talk to the pediatrician first — never cut a feed on your own by restricting.

### Can I start purees before 6 months so my baby drops the bottle?

Not on your own. The WHO recommends exclusive breastfeeding until 6 months, and Brazil's Ministry of Health dietary guide sets the same milestone for formula-fed babies: new foods from 6 months. Starting solids early doesn't make a baby 'drop' formula — in the first months of solids, food complements, it doesn't replace. Protocols for starting something between 4 and 6 months exist for specific situations, but that's an individual decision made by the pediatrician.

### What are the signs my baby is ready for solids?

The classic ones, which tend to line up close to 6 months: sitting with support while holding the head and trunk steady (a criterion of the SBP, the Brazilian Society of Pediatrics); active interest in food (following your fork, opening the mouth, reaching for it); loss of the tongue-thrust reflex (the one that pushes everything out of the mouth) and hand-to-mouth coordination — bringing objects to the mouth on purpose. Age alone isn't enough: it's age plus signs, confirmed at the 6-month checkup.
