How Much Should My Baby Eat? Feeding Guide by Age (0–12 Months)
A complete guide to how much babies should eat at every age from newborn to 12 months — covering breastfeeding, formula, and solids with AAP-based guidelines.
Srivishnu RamakrishnanApril 3, 202610 min readEvery new parent eventually stares at their baby wondering: is that enough? Too much? How do I even know? The answer changes considerably across the first year — a newborn's stomach holds about as much as a large grape, while a 10-month-old attacking a bowl of peas at the table is a different creature entirely.
Here's a clear breakdown of how much babies need at each stage, and the signs that tell you whether feeding is going well.
Newborns (0–4 Weeks)
The newborn stomach is genuinely tiny — about 5–7 ml at birth, expanding to 45–60 ml by day 7. This is why newborns feed so frequently.
| Age | Volume per feed | Feeds per day | Total daily intake |
|---|---|---|---|
| Day 1–2 | 5–7 ml (1–1.5 tsp) | 8–12 | ~30–60 ml |
| Day 3–4 | 22–27 ml (0.75–1 oz) | 8–12 | ~180–300 ml |
| Day 5–7 | 45–60 ml (1.5–2 oz) | 8–10 | ~360–600 ml |
| Week 2–4 | 60–90 ml (2–3 oz) | 8–10 | ~480–900 ml |

1–3 Months
This is the period of fastest weight gain in most babies' lives. A baby gaining 150–200 g per week needs consistent, frequent feeding to fuel it.
| Age | Volume per feed | Feeds per day | Total daily intake |
|---|---|---|---|
| 1 month | 90–120 ml (3–4 oz) | 7–8 | ~600–800 ml (20–27 oz) |
| 2 months | 120–150 ml (4–5 oz) | 6–8 | ~700–900 ml (24–30 oz) |
| 3 months | 120–180 ml (4–6 oz) | 5–7 | ~700–980 ml (24–32 oz) |
A useful rule of thumb for formula feeding: 2.5 oz per pound of body weight per day, up to a daily maximum of around 32 oz total, regardless of weight.
4–6 Months
Feeds become more efficient and predictable. Many babies establish a recognisable rhythm. The upper end of formula intake plateaus around this time.
| Age | Volume per feed | Feeds per day | Total daily intake |
|---|---|---|---|
| 4 months | 120–180 ml (4–6 oz) | 5–6 | ~700–980 ml (24–32 oz) |
| 5 months | 150–180 ml (5–6 oz) | 4–6 | ~700–980 ml (24–32 oz) |
| 6 months | 180–210 ml (6–7 oz) | 4–5 | ~700–980 ml (24–32 oz) |
Starting Solids: 6–9 Months
The introduction of solids doesn't replace milk — it supplements it. Breast milk or formula remains the primary nutrition source through the first year of life.
| Age | Milk feeds | Solid meals | Solid portion size |
|---|---|---|---|
| 6 months | 4–5 feeds | 1 meal/day | 1–2 tbsp puree |
| 7 months | 4 feeds | 1–2 meals/day | 2–4 tbsp per meal |
| 8 months | 3–4 feeds | 2–3 meals/day | 4–6 tbsp per meal |
| 9 months | 3–4 feeds | 2–3 meals/day | Progressing to finger foods |
Milk feeds continue at roughly 600–800 ml (20–27 oz) of formula per day, or breastfeeds 3–4 times per day.
9–12 Months: The Transition
By 9–10 months, many babies are ready for three meals a day plus milk feeds. The balance shifts gradually toward table foods.
| Age | Milk feeds | Meals | Snacks |
|---|---|---|---|
| 9 months | 3–4 feeds | 2–3 meals | 0–1 small snack |
| 10 months | 3–4 feeds | 3 meals | 1 snack |
| 11 months | 3 feeds | 3 meals | 1–2 snacks |
| 12 months | 2–3 feeds | 3 meals | 1–2 snacks |
By 12 months, the goal is three balanced meals with milk as a complement — transitioning toward whole cow's milk can begin at 12 months as the primary drink (breastfeeding continues as long as desired).
How to Tell If Baby Is Getting Enough
Numbers are useful guidelines, but your baby's behaviour and growth tell the real story.
Signs of adequate feeding:
- Producing 6+ wet diapers per day (under 6 months)
- Settling after feeds — not screaming with continued hunger cues
- Steady weight gain following their growth percentile
- Alert and active between feeds (not lethargic)
Signs to discuss with your doctor:
- Persistent hunger despite meeting average volume targets
- Significant weight loss or plateau lasting more than 2 weeks
- Consistently refusing feeds (not just a bad day)
- Vomiting after most feeds (may indicate reflux)

Never Force a Feed
Both under- and over-feeding have consequences. The most important principle at every age is responsive feeding — offering food when hunger cues appear, stopping when satiety cues appear.
Hunger cues in babies include rooting, sucking on hands, turning the head, and fussiness. Satiety cues include turning away from the breast or bottle, slowing the suck, becoming calm, and falling asleep.
Forcing a baby to finish a bottle they've pulled away from teaches them to ignore their satiety signals — a pattern that can persist well into childhood. For breastfeeding parents with the same intake anxiety, is breast milk enough covers the output signs that confirm adequate feeding.

Frequently Asked Questions
How many ounces should a 2-month-old eat per feeding?
Most 2-month-olds take 4–5 oz (120–150 ml) per bottle feeding, with feeds around 6–8 times per day. Total daily intake is typically 24–32 oz. Breastfed babies are harder to measure — the key sign is 6+ wet diapers per day and steady weight gain.
How do I know if my breastfed baby is eating enough?
The most reliable signs are wet and dirty diapers, contentment after feeds (not screaming hunger), and steady weight gain. In the first 6 weeks: 6–8 wet diapers per day and regaining birth weight by 2 weeks confirms adequate intake. After that, consistent percentile tracking is the best measure.
Can I overfeed a baby?
Breastfed babies are very difficult to overfeed — they self-regulate intake at the breast. Formula-fed and bottle-fed babies are easier to overfeed because flow is constant and fast. Signs of overfeeding include spitting up frequently after feeds, seeming uncomfortable, and gaining weight very rapidly above the 97th percentile.
How much solids should a 6-month-old eat?
At 6 months, solids are primarily for exploration and taste exposure — milk (breast or formula) remains the primary nutrition source. Offer 1–2 tablespoons of puree or soft foods at one meal per day. By 8–9 months, aim for 2–3 small meals. Quantity matters less than the experience of eating at this stage.
Should I wake a sleeping newborn to feed?
Yes — in the first 2 weeks, wake your newborn every 2–3 hours if they haven't fed on their own, even at night. This ensures adequate intake while your milk supply establishes and until birth weight is regained. After birth weight returns, you can let a healthy, growing baby sleep longer stretches.
