Quick answer: For the first 6 months, your baby needs only breast milk — fed on demand, whenever they show hunger cues, not by the clock. The World Health Organization (WHO) and the Indian Academy of Pediatrics (IAP) recommend exclusive breastfeeding for the first 6 months, then continued breastfeeding alongside solids up to 2 years and beyond. There is no fixed “amount” for a breastfed baby — you follow your baby, not a number. If you formula-feed (because of medical need or your own circumstances), a rough guide is about 150 ml per kg of body weight per day, split across feeds — but the exact amount must be set with your pediatrician. From 6 months, milk continues while you add small amounts of solids that grow over the next 6 months. The most reliable sign your baby is eating enough is steady weight gain and plenty of wet nappies — not the volume you measure.
First, the Important Bit: Breast Milk Is the Norm
Breast milk is the first and best food for every baby. WHO and IAP both recommend exclusive breastfeeding for the first 6 months — no water, no formula, no honey, no top-feeds — and continued breastfeeding up to 2 years and beyond alongside family foods.
This article explains formula amounts only because some families need them — for example, when there is a genuine medical reason, low supply that hasn’t responded to support, or other personal circumstances. If you are using formula, that is a decision to make with your pediatrician, and your baby is still loved and fed.
A note on the law (India): Under India’s Infant Milk Substitutes (IMS) Act, 1992, the promotion of any breast-milk substitute, feeding bottle or brand is prohibited. We therefore do not name or recommend any formula brand anywhere on this site. Any formula amounts below are general medical guidance, not an endorsement to use formula.
0–6 Months: Breastfeeding On Demand (Not by the Clock)
For the first half-year, a breastfed baby decides how much they eat. Your job is to offer the breast whenever they signal hunger, day and night, and let them feed until they come off on their own.
Feed on cues, not a schedule
Watch your baby, not the clock. Early hunger cues include:
- Stirring, opening the mouth, turning the head (rooting)
- Bringing hands to the mouth, sucking on fists
- Soft fussing and squirming
Crying is a late sign — try to feed before your baby gets to that point, as a very upset baby latches less well.
How often?
A newborn typically feeds 8–12 times in 24 hours, often clustered. This is normal and is exactly how your baby builds and protects your milk supply. Frequent feeding does not mean you have too little milk.
Don’t ration, time, or stretch out breastfeeds in the early weeks. “On demand, both day and night” is the WHO guidance — and it’s what keeps supply matched to your baby’s needs.
What about water?
An exclusively breastfed baby under 6 months needs no extra water, even in Indian summers. Breast milk is about 88% water and meets all their fluid needs. Extra water can fill a small tummy and displace nutrition.
If You Formula-Feed: Amounts by Age
The figures below are general guidance for a healthy, term, formula-fed baby, to be confirmed and adjusted by your pediatrician. Never over-concentrate or dilute feeds, and always make up feeds exactly per the tin’s instructions.
Make feeds up safely (powdered formula is not sterile). Powdered infant formula can contain harmful bacteria such as Cronobacter. To kill them, reconstitute the powder with water that has been boiled and then cooled to about 70°C (water that has been off the boil for no more than about 30 minutes — not lukewarm water). Then cool the made-up feed to body temperature under a running tap before giving it. Don’t make feeds in advance and leave them standing out; make each feed fresh and discard any leftover at the end of a feed. (WHO: Safe Preparation, Storage and Handling of Powdered Infant Formula, 2007.)
The “150 ml per kg per day” rule of thumb
A common pediatric starting point is roughly 150 ml of prepared formula per kilogram of body weight per day for young infants (and up to about 180 ml/kg/day in the early weeks), divided across feeds.
- Example: a 4 kg baby → about 4 × 150 = 600 ml across the day, split over (say) 7–8 feeds ≈ 75–90 ml per feed.
Big caveat: this is a guide, not a target. Babies are not machines — some feeds are bigger, some smaller. Feed responsively: offer, let your baby take what they want, and stop when they show they’re full (turning away, slowing down, releasing the teat). Don’t force the last bit “to finish the bottle.” The amount per kg drops as your baby grows older and heavier, and changes again once solids start.
An upper limit: most babies should not take more than about 960 ml (32 oz) of formula in 24 hours. If your baby consistently wants more than this, talk to your pediatrician rather than increasing the amount further.
| If formula-fed: typical age range | Approx. per feed | Approx. feeds / day |
|---|---|---|
| 0–1 month | 60–90 ml | 6–8 |
| 1–2 months | 90–120 ml | 5–7 |
| 2–4 months | 120–150 ml | 5–6 |
| 4–6 months | 150–180 ml | 4–5 |
| 6–12 months | 180–240 ml | 3–4 (solids fill the gap) |
These are general AAP/pediatric ranges for healthy term infants and will vary widely between babies. Total daily intake for many babies sits around the 150 ml/kg/day mark in the early months, tapering thereafter. Confirm your baby’s amounts with your pediatrician.
Don’t out-feed a bottle. Over-feeding is easier with a bottle than at the breast. Use paced bottle-feeding, watch for fullness cues, and never prop the bottle.
6–12 Months: Starting Solids — Alongside Milk, Not Instead Of It
At around 6 months (not before), milk alone no longer meets all your baby’s needs — especially for iron — so you add complementary foods. Crucially, milk (breast or formula) stays the main source of nutrition through the first year. Solids are added on top, building up gradually.
How much, and how it builds
Start small and increase texture and quantity over the months:
- 6 months: start with 2–3 teaspoons once a day, working up to a few tablespoons. Smooth purées and mashes.
- 7–8 months: 2–3 meals a day, plus 1–2 healthy snacks; mashed and lumpy textures, soft finger foods.
- 9–11 months: 3 meals a day + 1–2 snacks; finely chopped foods and finger foods. By 12 months your baby can eat soft versions of most family food.
Let your baby’s appetite lead the amount. A baby may eat a lot one day and little the next — that’s normal.
India-appropriate first foods
Good, affordable Indian first foods include:
- Ragi (finger millet) porridge — soft, iron- and calcium-rich; a classic Indian weaning food
- Dal water, then mashed dal — protein
- Mashed khichdi (rice + moong dal, soft and well-cooked) — a complete, easy meal
- Mashed/steamed vegetables — potato, carrot, bottle gourd (lauki), pumpkin
- Mashed fruit — banana, well-cooked apple/pear, papaya
- Mashed sooji (rava)/idli, curd (after 6 months) in small amounts
Add iron-rich foods early (ragi, dal, well-cooked whole egg, mashed greens) — iron is the single most important nutrient solids provide at this stage.
Avoid before 1 year: cow’s milk as a main drink, honey (risk of infant botulism), added salt and added sugar, whole nuts and other choking hazards. Start one new food at a time.

Responsive Feeding: The Golden Rule at Every Age
Whether it’s breast, bottle or spoon, the principle is the same — feed responsively:
- Offer when your baby is hungry; stop when they show they’re full.
- Never force-feed, never chase with a spoon, never insist on finishing a bottle.
- Eat together, make it calm and positive, no screens or distractions.
- Trust that a healthy baby regulates their own intake over days, not single meals.
Forcing more food doesn’t make a baby grow faster — it teaches them to ignore their own fullness. The amount your baby takes, set by their own appetite, is almost always the right amount.
How Do I Know My Baby Is Getting Enough?
You can’t measure breast milk, and you shouldn’t obsess over bottle volumes. Look at your baby, not the numbers:
- Wet nappies: from about day 5, 6 or more wet nappies in 24 hours with pale, odourless urine is the classic sign of enough fluid and milk.
- Stools: regular soft stools (breastfed babies’ patterns vary widely).
- Steady weight gain along their own curve on the WHO chart (see Baby Weight Gain in the First Year).
- Alert and active when awake; settles and is content after most feeds.
- Meeting milestones and growing in length and head size.
A baby who feeds well, has plenty of wet nappies, is alert, and is gaining weight is almost always getting enough — regardless of how much you think you “saw” them take.
Feeding Amounts by Age — Quick Chart
| Age | Milk (the main food) | Solids | Typical feeds/meals |
|---|---|---|---|
| 0–1 month | Breast on demand (or, if formula-fed, ~60–90 ml/feed) | None | 8–12 breastfeeds (or 6–8 bottles) / 24h |
| 1–3 months | Breast on demand (or ~90–150 ml/feed) | None | On demand / 5–7 bottles |
| 3–6 months | Breast on demand (or ~120–180 ml/feed) | None | On demand / 5–6 bottles |
| 6–8 months | Breast/formula continues as main food | Start 2–3 tsp → few tbsp; 2–3 meals + snacks | Milk on demand + 2–3 solid meals |
| 9–11 months | Breast/formula still the main source | 3 meals + 1–2 snacks; chopped/finger foods | Milk + 3 meals |
| 12 months | Breastfeeding continues (alongside family food) | 3 meals + 2 snacks; soft family food | Milk + 3 meals + snacks |

Read it as a range, not a quota. Healthy babies vary enormously in how much they eat. Follow your baby’s cues and your baby’s growth curve, not another baby’s amounts.
When to See Your Doctor
Feeding problems and dehydration can become serious quickly in small babies. Contact your pediatrician if you notice:
- Poor feeding — refusing feeds, feeding very weakly, or far fewer feeds than usual
- Fewer than 6 wet nappies a day (after day 5), or dark, strong-smelling urine
- Signs of dehydration — dry mouth/lips, sunken eyes, a sunken soft spot (fontanelle), no tears when crying, unusual sleepiness or floppiness
- Poor weight gain or weight loss outside the normal newborn dip
- Persistent vomiting (especially forceful), or green vomit
- Choking, gagging that doesn’t settle, or breathing trouble during feeds
- A baby who is lethargic, very irritable, or hard to wake
For any emergency — a baby who is choking, struggling to breathe, very floppy, or won’t wake — call 112 (national emergency) or 108 (ambulance) immediately, or go to the nearest hospital. Don’t wait.
Frequently Asked Questions
How much milk does a newborn need?
A newborn’s stomach is tiny — only 5–7 ml on day 1, growing to roughly 60 ml per feed by the end of the first week. Breastfeed on demand, 8–12 times a day, and your supply matches your baby. If you formula-feed, start at about 60 ml per feed and adjust with your pediatrician.
How do I calculate how much formula my baby needs?
A common starting guide is about 150 ml of prepared formula per kg of body weight per day, divided across feeds. For a 4 kg baby that’s roughly 600 ml a day. This is only a guide — feed responsively, watch for fullness, and confirm the right amount with your pediatrician.
Do I need to feed my baby water in summer?
No. An exclusively breastfed baby under 6 months needs no extra water, even in Indian heat — breast milk provides all the fluid they need. Water can be introduced in small sips once solids start at 6 months.
When should I start solids, and how much?
At around 6 months — not before. Start with 2–3 teaspoons once a day (ragi porridge, mashed dal, mashed banana, soft khichdi) and build up gradually. Milk stays the main food through the first year; solids are added on top.
My baby suddenly wants to feed all the time — is my milk not enough?
Usually not. Frequent feeding, especially during growth spurts, is normal and is how your baby boosts your supply. As long as wet nappies and weight gain are fine, your milk is enough. If you’re worried, get feeding assessed rather than reaching for formula.
Is it bad to force my baby to finish a bottle?
Yes — avoid it. Over-feeding is easier with a bottle, and forcing feeds teaches babies to ignore their own fullness. Stop when your baby shows they’re done. Their appetite is the best guide to the right amount.
This article is general information for parents in India and follows WHO, IAP and AAP infant-feeding guidance. It is not a substitute for an in-person assessment by your pediatrician, who knows your baby’s full history. Breast milk is the recommended food for infants; formula amounts here are general guidance for families who formula-feed and must be individualised by your doctor. For any urgent concern — poor feeding, signs of dehydration, choking, or a baby who won’t wake — contact your pediatrician or the nearest hospital immediately, or call 112 (national emergency) or 108 (ambulance).
