Formula Amounts for Babies 0–6 Months: A Month-by-Month Chart
If you are searching for formula milk for baby 0-6 months quantity, here is the short version: daily totals climb fast for three months, then level off near 32 oz (950 ml), while each bottle gets bigger and feeds get fewer. This formula chart for 0–6 months uses the 150 ml/kg/day starting point and shows ml and oz for each month.

Formula Chart 0–6 Months (ml and oz)
Weights are typical mid-range values; healthy babies vary a lot. Daily totals for months 1–3 are weight in kg × 150 ml. From month 4 the table shows the practical ceiling of about 32 oz rather than the raw multiplication (see below).
| Age | Typical weight | Daily total | Per feed | Feeds/day |
|---|---|---|---|---|
| 1 month | 4.0 kg | 600 ml · ~20.3 oz | 75 ml · ~2.5 oz | 8 |
| 2 months | 5.0 kg | 750 ml · ~25.4 oz | 107 ml · ~3.6 oz | 7 |
| 3 months | 6.0 kg | 900 ml · ~30.4 oz | 129 ml · ~4.4 oz | 7 |
| 4 months | 6.7 kg | ~950 ml · ~32 oz | 158 ml · ~5.3 oz | 6 |
| 5 months | 7.3 kg | ~950 ml · ~32 oz | 190 ml · ~6.4 oz | 5 |
| 6 months | 7.8 kg | ~950 ml · ~32 oz | 190 ml · ~6.4 oz | 5 |

How Much Formula for a Baby by Month?
Month 1:small, frequent bottles of about 60–90 ml (2–3 oz) every 3 hours or so. The very first days are much smaller, and the 150 ml/kg figure only applies once feeding is established.
Months 2–3:bottles of roughly 90–150 ml (3–5 oz) as the stomach grows and babies stretch to 3–4 hours between feeds. See the week-by-week chart to 3 months for finer detail.
Months 4–6:bottles of about 150–240 ml (5–8 oz), 4–6 times a day. Month pages: 4 months, 5 months and 6 months.
Worked 150 ml/kg/day Example
Worked example
A 5 kg baby at about 2 months: 5 × 150 = 750 ml per day (about 25 oz). Across 7 feeds: 750 ÷ 7 ≈ 107 ml (3.6 oz) per feed. Across 6 feeds: 125 ml (4.2 oz).
Pounds? Multiply by 2.5 oz per pound instead, or divide pounds by 2.2 to get kg. The 150 ml/kg/day explainer covers the maths in more depth.
Why Daily Formula Totals Plateau After 4 Months
A 7.8 kg baby multiplied by 150 gives about 1170 ml (40 oz), yet most formula-fed babies do not need more than about 32 oz (950 ml) a day. Appetite and stomach capacity do not rise in step with weight, and solid foods begin to add energy around 6 months. So the multiplication is a starting estimate, not a target to hit. If your baby is regularly taking much more or much less than the chart suggests but is gaining weight and content, that is worth mentioning at a check-up rather than worrying about.
Formula Feeding Frequency 0–6 Months
- 0–1 month:about 7–8 feeds, and newborns should not usually go much past 4 hours between feeds.
- 2–3 months:about 6–7 feeds.
- 4–6 months:about 4–6 feeds, and some babies drop the overnight feed.
Hunger cues (rooting, hands to mouth, fussing) and fullness cues (slowing, turning away, relaxed hands) matter more than the clock. Paced bottle feeding helps babies stop when full. The feeding schedule by age guide goes further.
Is My Baby Getting Enough Formula?
- Wet diapers:at least 5–6 a day.
- Weight: steady gain along their own growth curve at check-ups.
- Contentment: relaxed and alert between feeds.
Contact your pediatrician if diapers drop, your baby is hard to wake for feeds, or weight gain stalls. Always mix formula exactly as the label says. This chart is general information, not individual medical advice.

Frequently Asked Questions
How much formula milk should a baby have from 0 to 6 months?
The AAP and CDC starting point is about 150 ml per kg of body weight per day (2.5 oz per pound). For typical weights that is roughly 600 ml (20 oz) a day at 1 month, 900 ml (30 oz) at 3 months, and about 950 ml (32 oz) from 4 to 6 months, where intake plateaus. Treat the numbers as an estimate and follow your baby's hunger and fullness cues.
How much formula for a baby by month?
Typical per-feed amounts are about 75 ml (2.5 oz) at 1 month, 107 ml (3.6 oz) at 2 months, 129 ml (4.4 oz) at 3 months, 158 ml (5.3 oz) at 4 months, and 190 ml (6.4 oz) at 5 and 6 months. The number of feeds drops from about 8 to about 5 a day over the same period.
What does a formula chart for 0-6 months look like?
It starts with small, frequent feeds of 60-75 ml every 3 hours or so, climbs to 120-150 ml by about 3 months, and reaches 180-240 ml per feed with 4-5 feeds a day by 6 months. Daily totals rise quickly in the first three months, then level off near 32 oz (950 ml).
Why does formula intake stop rising after 4 months?
Weight keeps climbing, but a baby's appetite and stomach capacity do not scale in a straight line. Most formula-fed babies do not need more than about 32 oz (950 ml) a day, so multiplying a heavier baby's weight by 150 can overshoot. If your baby consistently wants far more or less, mention it at the next check-up.
How much formula does a 6-month-old need once solids start?
Most 6-month-olds still take about 4-5 formula feeds of 180-240 ml (6-8 oz). Early solids are tiny tasting portions, so milk stays the main source of nutrition and totals only fall gradually in the following months.
Does the same chart work for expressed breast milk?
Bottle volumes of expressed milk follow similar amounts, but breastfed babies often settle at lower daily totals (around 750-800 ml) because breast milk is digested differently. Babies feeding directly at the breast are judged by diapers, weight gain and contentment rather than ounces.
