How Much Should a Baby Actually Eat? (Less Than You Think)
Portion sizes by age, why milk still dominates until 12 months, and why the answer to "is she eating enough" is almost always yes.

Parents worry about this more than almost anything else, and the answer is consistently reassuring: less than you think, and it is almost certainly fine.
Milk is still the main event
The most common misunderstanding is that solids replace milk. They do not — not for a long time.
Rough guide to daily milk intake:
| Age | Breast milk or formula | Food’s share of nutrition |
|---|---|---|
| 6 months | ~700–900 ml | Almost none |
| 7–8 months | ~700–800 ml | Small |
| 9–11 months | ~600–700 ml | Growing |
| 12 months | ~500–600 ml, transitioning | Roughly half |
| 12+ months | ~350–400 ml whole cow’s milk | Most |
Breastfed babies self-regulate and there is no need to count. The point is that milk is not something you take away when food arrives. Food is added around it, and the balance shifts slowly across the second half of the first year.
Portions by age
These are starting points, not targets. Serve them, and let your baby decide how much of it goes in.
6 to 8 months — one to two meals a day
Start with 1 to 2 tablespoons per meal. It will look absurdly small and most of it will not be eaten. That is the correct amount and the correct outcome.
Build gradually toward 2 to 4 tablespoons by 8 months.
9 to 11 months — two to three meals a day
Around 4 to 6 tablespoons per meal, plus a snack. This is where volume genuinely picks up, and where the pincer grasp makes self-feeding much more productive.
12 to 24 months — three meals plus one or two snacks
The useful rule of thumb: about a quarter of an adult portion, or roughly a tablespoon of each food per year of age as a starting serve. A toddler’s stomach is about the size of their fist.
Why appetite falls off a cliff at one
This catches almost every parent out.
A baby roughly triples their birth weight in the first year. In the second year they gain around 2 to 3 kg total. Growth slows dramatically, and appetite follows it down.
A 13-month-old who is eating noticeably less than they did at 11 months is not developing a problem. They are eating in proportion to how fast they are growing. This is the single most common trigger for “my toddler has stopped eating” and it is almost always physiology rather than pathology.
Look at the week, not the meal
Babies and toddlers regulate their intake across days, not individual meals. A day where nothing gets eaten is routinely followed by a day where everything does.
If you tracked a toddler for a week and averaged it, you would almost always find something reasonable. If you track a single lunch, you will worry.
The reliable signals are:
- Growth tracking along their own centile. Not a particular centile — their own. A baby steadily on the 9th is doing exactly as well as one steadily on the 91st.
- Wet nappies — six or more a day.
- Alert, active, developing normally.
Those tell you far more than a plate ever will.
What matters more than quantity
Iron at most meals. This is the one nutrient where a small volume genuinely creates a problem, because the requirement is high — around 11 mg a day from 6 to 12 months — and the eating volume is low. Beef, lentils, iron-fortified cereal, with a vitamin C food alongside plant iron.
Calorie density. A baby’s stomach fills before their energy needs are met, so what is in the volume matters. Olive oil stirred into vegetables, full-fat yogurt, avocado, thinned nut butter. Low-fat anything is for adults.
Variety. Twenty foods met in the first month is a better indicator than volume, both for nutrition and for how the next two years go.
Allergen maintenance. Each of the nine, roughly twice a week, ongoing.
Signs it is worth checking
Talk to your pediatrician or health visitor if:
- Growth has flattened or is crossing down through centile lines.
- Fewer than six wet nappies a day.
- Your baby seems lethargic or unusually pale.
- Vomiting, or persistent distress with feeds.
- No progression in texture past smooth purée by around 10 to 12 months.
- Food intake has been dropping for weeks rather than days.
The short version
At 6 months, a teaspoon is a good meal. At 12 months, a quarter of an adult portion. In between, it climbs on its own without anyone pushing.
Serve the food. Let them decide. Watch the growth chart rather than the plate.
Questions parents ask
How much milk should a baby have while eating solids?
Roughly 700–900 ml a day of breast milk or formula at 6 months, tapering toward 500–600 ml by 12 months as food takes over. After 12 months, around 350–400 ml a day of whole cow's milk. Milk should not be dropped when solids start — it is added to, not replaced.
My baby only eats two spoonfuls. Is that enough?
At 6 to 7 months, yes. Milk is still supplying essentially all the nutrition and the point of early solids is practice. Volume climbs steadily through the second half of the first year without anyone needing to push it.
How do I know if my baby is eating enough?
Steady growth along their own centile, plenty of wet nappies, and a baby who is alert and developing normally. That is the answer, not what happened at lunch. If growth is tracking, intake is adequate — however little it looks.
