Kendamil First Infant Milk Ready to Feed: Ounces Per Feeding by Age
Ready-to-feed first infant milk, including Kendamil's liquid range, takes the scoops out of bottle prep, but parents still ask the same question: how much per feed? The reassuring answer is that a prepared ready-to-feed bottle is the same strength as correctly mixed powder, so the usual guidance applies. This guide turns the 150 ml/kg/day starting point into ml and oz per feeding by age and weight, and covers the handling basics that are different for liquid formula.

How Much Kendamil First Infant Milk Ready to Feed Per Feed?
First infant milk is designed as a complete feed from birth, whether it comes as powder or ready-to-feed liquid. Health guidance for bottle feeding, such as the CDC, HealthyChildren.org and NHS pages listed below, describes amounts by age and body weight rather than by brand. A common starting point is about 150 ml per kg of body weight per day(roughly 2.5 oz per pound), shared across the day's feeds.
Brand packs may print their own feeding tables. If the label on your bottle differs from this page, follow the label and your health professional, and treat this guide as a way to understand the reasoning. Our UK and Australia formula guide covers on-tin guidance for other brands.
Worked 150 ml/kg/day Example
Worked example: 4 kg baby, ready-to-feed bottles
4 kg × 150 ml = 600 ml per day (about 20.3 oz). Over 8 feeds: 600 ÷ 8 = 75 ml (2.5 oz) per feed. Over 7 feeds: about 86 ml (2.9 oz) per feed. Pour only what the feed needs, plus a little extra if your baby often asks for more.
Working in ounces? Multiply the weight in pounds by 2.5 to get the daily total. A 9 lb baby is about 22.5 oz a day.
Ready to Feed Formula Ounces Per Feeding by Age
Use this table to find a typical weight and per-feed amount for your baby's age. Babies vary a lot, so use the row closest to your baby's actual weight when you can.
| Age | Typical weight | Daily total | Feeds | Per feed |
|---|---|---|---|---|
| 1–2 weeks | 3.5 kg / 7.7 lbs | 525 ml · ~17.8 oz | 8 | 66 ml · ~2.2 oz |
| 1 month | 4 kg / 8.8 lbs | 600 ml · ~20.3 oz | 8 | 75 ml · ~2.5 oz |
| 2 months | 5 kg / 11 lbs | 750 ml · ~25.4 oz | 7 | 107 ml · ~3.6 oz |
| 3–4 months | 6 kg / 13.2 lbs | 900 ml · ~30.4 oz | 6 | 150 ml · ~5.1 oz |
| 5–6 months | 7 kg / 15.4 lbs | ~960 ml · ~32 oz (typical ceiling) | 5–6 | 160–190 ml · ~5.4–6.5 oz |

How Much Ready to Feed Formula for a Newborn?
In the first few days a newborn's stomach is tiny, and feeds are often only 30–60 ml (1–2 oz). Amounts climb quickly over the first one to two weeks as your baby wakes up and feeds more often. Ready-to-feed formula is convenient at this stage because you can pour a small amount for each feed without measuring powder. See newborn milk intake in the first six weeks for the week-by-week picture.
Why Parents Choose Ready-to-Feed First Infant Milk
Liquid formula removes mixing errors, and because it is sold sterile, the CDC suggests considering it for babies at higher risk of infection, such as premature babies, those under 2 months or those with weakened immune systems. Powder is not sterile, which is why water temperature and clean preparation matter so much for powdered formula. The trade-off is cost and bulk. Our ready-to-feed vs powdered formula comparison works through the arithmetic.
Handling Ready-to-Feed Bottles Safely
- Do not add water. Ready-to-feed is already the correct strength. Diluting it dilutes the nutrition.
- Check the pack. Opening, storage and use-by instructions differ between products; follow the label for part-used bottles.
- Warming is optional. If you warm it, use warm water in a jug or bottle warmer, not a microwave, and test a few drops on your wrist.
- Discard leftovers from a feed.Milk that has been in your baby's mouth should not be saved for later.
- Clean the nipple and bottle between feeds, as for any bottle feeding.
Mixing powder and ready-to-feed in the same bottle is not recommended. For water questions with powder, see distilled or purified water for baby formula.
Is My Baby Getting Enough?
Follow hunger and fullness cues rather than finishing every bottle. Early hunger cues include rooting and hands to mouth; fullness cues include slowing down, turning away or relaxing hands. Look for at least 5–6 wet diapers a day after the first week and steady weight gain. Contact your pediatrician or health visitor if feeds drop, your baby is hard to wake, or weight gain stalls. This guide is general information, not individual medical advice. More in signs baby is eating enough.

Frequently Asked Questions
How much Kendamil first infant milk ready to feed per feed?
Ready-to-feed first infant milk is already mixed, so the amounts are the same as for any formula: about 150 ml per kg of body weight per day as a starting point. A 4 kg baby needs roughly 600 ml (20 oz) a day, or about 75 ml (2.5 oz) per feed across 8 feeds. Your baby's cues and your health professional's advice come first.
Is ready to feed formula amount the same as powdered formula?
Yes. A prepared bottle of ready-to-feed formula and a correctly mixed bottle of powder are the same strength, so ml and oz amounts per feed do not change. Never add water to ready-to-feed formula, because diluting it reduces the nutrition your baby receives.
How much ready to feed formula for a newborn?
In the first days newborns take small amounts, often 30 to 60 ml (1 to 2 oz) per feed, rising over the first one to two weeks. A baby around 3.5 kg works out to about 66 ml (2.2 oz) per feed over 8 feeds at 150 ml/kg/day.
How many ounces of ready to feed formula per feeding by age?
Typical per-feed amounts rise from roughly 2 to 3 oz (60 to 90 ml) at one month to about 4 to 6 oz (120 to 180 ml) at four to six months. The table above links each age to a typical weight and a per-feed range.
Can I warm ready to feed formula, and how long can it sit out?
Many babies are happy with it at room temperature. If you warm a bottle, use a jug of warm water rather than a microwave, which heats unevenly, and test a few drops on your wrist. Follow the storage and use-within times on the pack for opened and part-used bottles, and throw away leftover milk from a feed instead of re-offering it later.
Does a baby need more than 150 ml/kg/day on ready to feed formula?
It is a starting point, not a target. Some healthy babies take somewhat more or less, and amounts level off as solids begin around six months. Steady weight gain, wet diapers and a content baby matter more than hitting the number.
