How Much Milk Does an 11-Month-Old Need?

How Much Milk Does an 11-Month-Old Need?

The standard starting point used by the American Academy of Pediatrics (AAP) and the CDC is 150 ml of milk per kilogram of body weight per day — written as 150 ml/kg/day. Most 11-month-olds weigh between 9.5 and 11.5 kg (roughly 20.9–25.4 lbs), which puts the weight-based daily milk target at approximately 1425–1725 ml per day (about 48–58 oz).

This rule applies equally to infant formula and to expressed breast milk. The caloric density of standard formula (about 67 kcal per 100 ml) closely matches mature breast milk (roughly 65–70 kcal per 100 ml), so the same volume target covers daily fluid and energy needs for both milk types.

An important nuance at eleven months: with three solid meals fully established and portions growing meaningfully, actual daily milk consumption typically falls noticeably below the full weight-based calculation. The CDC notes that by 8–10 months many babies settle at 600–900 ml of milk per day alongside solid food — a healthy, baby-led reduction driven by growing caloric intake from meals. The 150 ml/kg/day figure remains a useful upper reference ceiling, but a baby thriving on three solid meals and taking somewhat less milk is almost certainly feeding normally.

The figure is a starting estimate, not a strict daily quota. A baby growing steadily along a consistent growth curve and producing at least 5–6 wet diapers per day is almost certainly feeding adequately — regardless of whether the ml figure precisely matches the calculation.

How Much Formula for an 11-Month-Old?

Formula-fed 11-month-olds typically take 180–240 ml (6–8 oz) per feed across 3–4 feeds in 24 hours, alongside solid meals. The exact per-feed amount depends on your baby's weight, how many milk feeds they take, and how much solid food they are eating.

As solid food portions grow, it is natural and expected for formula intake to trend gradually lower. This reduction should always be baby-led: if your baby consistently drains every bottle and shows hunger cues, maintain or modestly increase the per-feed amount. If they regularly leave formula behind after a solid sitting, do not push them to finish. Responsive feeding protects against both underfeeding and overfeeding.

At 11 months, continue using infant formula rather than whole cow's milk as your baby's primary milk drink. The AAP recommends waiting until 12 months to introduce whole cow's milk as a replacement for formula or breast milk.

How Much Breast Milk for an 11-Month-Old?

The 150 ml/kg/day calculation applies to expressed (pumped) breast milk in the same way it applies to formula. For a 10.0 kg baby, that is a calculated target of 1500 ml per day — though in practice many breastfed babies this age take considerably less while growing well.

Research on exclusively breastfed babies shows that total daily breast-milk intake often plateaus near 750–800 ml per day by six to eight weeks and remains roughly stable regardless of further weight gain. A breastfed 10.0 kg baby consuming around 700–900 ml per day alongside solid meals is almost certainly meeting their needs — the weight-based figure can overstate requirements for directly breastfed babies at this age.

If you are nursing directly at the breast, total volume is not measured at each feed. Rely on indirect markers of adequate intake: at least 5–6 wet diapers per day, regular stools, and steady weight tracking. The WHO and AAP both recommend continuing to breastfeed alongside solid foods through at least 12 months — and longer if both mother and baby wish to continue.

11-Month-Old Feeding Amount Lookup Table

The table below uses the 150 ml/kg/day rule across common weights for 11-month-olds. Find your baby's approximate weight, then use the column matching your daily milk feed count as a per-feed starting point. With three solid meals established, actual daily intake may sit below the full calculated total — this is healthy and expected.

For an instant calculation with your baby's exact weight and feed count, open the Baby Milk Calculator.

If your baby's weight falls between two rows, divide your exact daily total (weight in kg × 150) by your daily milk feed count. For example, a 10.8 kg baby: 10.8 × 150 = 1620 ml daily; across 3 feeds that is 1620 ÷ 3 = 540 ml (~18.3 oz) per feed.

How Often Should an 11-Month-Old Eat?

At eleven months, most babies take milk 3–4 times per 24 hours, roughly every 3–4 hours during the day, alongside three solid food sittings. The majority have dropped overnight milk feeds entirely, consolidating sleep into one long stretch — though individual patterns vary.

A typical 11-month feeding day might look like: morning milk feed on waking, breakfast solids 20–30 minutes later, a midday milk feed before or after lunch solids, a dinner sitting, and an evening milk feed before bed. Many babies comfortably consolidate to three milk feeds; others still prefer four. Some 11-month-olds also begin having a small snack between meals — soft fruit, cheese, or yogurt — which may slightly reduce the volume of the next milk feed.

Formula-fed babies often go slightly longer between milk feeds than breastfed babies because formula empties from the stomach more slowly. Follow hunger and fullness cues — early hunger cues include hand-to-mouth movements, rooting, and increased alertness. Crying is a late hunger cue.

When Can I Switch from Formula to Cow's Milk?

The AAP recommends waiting until 12 months of age before introducing whole cow's milk as your baby's primary milk drink. At 11 months, continue with infant formula or breast milk as normal.

The reasoning behind the 12-month guideline is straightforward: cow's milk is high in protein and certain minerals that, in large quantities, place more demand on an infant's kidneys than formula or breast milk. Cow's milk also lacks adequate iron in a bioavailable form, and regular early consumption can contribute to iron-deficiency anemia. Infant formula is specifically designed to match an infant's nutritional needs until the first birthday.

Once your baby reaches 12 months, the transition can happen gradually over one to two weeks. Many families find it easiest to replace one formula feed at a time with a cup of whole cow's milk, allowing the baby's palate and digestion to adjust. Bottles are also typically phased out toward a cup around this time, in line with AAP guidance.

If you are breastfeeding, there is no equivalent “switch” required at 12 months — you and your baby can continue nursing as long as you both wish, alongside an expanding solid food diet.

How Solid Meals Shape Milk Needs at 11 Months

Eleven months is the final stretch of the transition that began around six months: solid food delivers increasing nutrition, yet milk remains the primary nutritional foundation through the first birthday. Two principles from the AAP and WHO are especially important:

• Milk stays primary through 12 months. Even with three solid meals well established, breast milk or formula remains the primary source of calories, fat, protein, iron, and vitamins through the first birthday. Solid foods complement milk; they do not yet replace it as the primary nutrition source.
• A meaningful reduction in milk volume is normal. The CDC notes that by 8–10 months many babies are taking 600–900 ml of milk per day alongside growing solid meals. If your 11-month-old is eating well at three solid sittings and taking noticeably less milk than the full calculation predicts, that is healthy appetite self-regulation — not a feeding problem.

At 11 months, many babies are enthusiastic and capable self-feeders: pincer grasp is well refined, and soft finger foods, family meals adapted in texture, and small snacks are all appropriate. Growing food variety and portion size at solid sittings naturally reduces milk appetite, and that is the intended progression. If you are navigating the texture transition or wondering about allergen timing, the When to Start Solid Foods guide covers the broader introduction arc across the first year.

Signs Your 11-Month-Old Is Getting Enough Milk

The AAP and CDC both emphasize that observable signs of adequate intake are more meaningful than matching a calculated volume. At eleven months, look for:

• Wet diapers: At least 5–6 wet diapers per day remains the most reliable hydration marker. Stool patterns change significantly once solid foods are well established, making wet diaper count the more useful independent indicator at this age.
• Steady weight gain: Most 11-month-olds gain roughly 70–90 g (about 2.5–3 oz) per week — a gradually slowing rate compared with earlier months. Tracking consistently along any growth percentile is more meaningful than reaching a specific weight target.
• Settles between feeds: A well-fed baby typically relaxes after a feed and has calm or alert periods before the next hunger cue.
• Alert and engaged: Strong interest in surroundings, social interaction, babbling, pointing, and purposeful play all signal a well-nourished baby.
• Active motor development: Cruising along furniture, pulling to stand, first steps in many babies, and advanced pincer grasp are all positive indicators of adequate energy and growth.

If diaper counts are persistently low, weight gain has stalled, or the baby seems persistently unsettled after every feed, speak with your pediatrician before making independent feeding changes. A baby who regularly leaves milk in the bottle and shows clear fullness cues after a solid sitting should not be encouraged to finish — responsive feeding protects against overfeeding.

The Bottom Line

Most 11-month-olds have a weight-based daily milk target of 1425–1725 ml (48–58 oz), calculated as 150 ml × body weight in kg. Dividing that total by 3–4 milk feeds gives a per-feed starting point of roughly 356–575 ml (12–19 oz), depending on weight and feed count.

With three solid meals now well established, actual intake often tracks meaningfully below the full calculation — many thriving 11-month-olds take 600–900 ml per day alongside three solid sittings. That is healthy and expected. Continue with infant formula or breast milk through twelve months: the AAP recommends waiting until the first birthday to introduce whole cow's milk as the primary drink.

Let your baby's appetite guide the balance: offer milk at regular intervals, do not restrict it to push solids, and trust fullness cues when they leave a bottle unfinished. Wet diapers, a steady weight curve, and a baby who is curious and active are the real evidence that the amount is right.
