I've lost count of how many parents have told me their toddler "lives on milk" and won't touch a meal. Almost every time, when we total up what's actually going into the cup or bottle each day, milk is filling a gap that food should be filling instead. Drinks feel like the easy, safe part of feeding a toddler, so they're the bit that quietly gets overlooked. Here's what I tell parents in clinic, question by question.
The quick answer:
- Milk: around 350ml (12oz) a day for a toddler aged 1 to 3, or the equivalent in dairy foods like cheese and yoghurt.
- Water: roughly 6 to 8 small cups offered through the day.
Read on for how that breaks down by age, and what to do if your toddler won't touch milk at all.
How much milk should a toddler have a day?
Around 350ml, roughly 12oz, is the figure I work to for a toddler once they're eating three meals and a couple of snacks a day. That can be whole cows' milk from 12 months, given as a drink or used in cooking, and it doesn't all need to come from a beaker: some of it can come from cheese and yoghurt, which I cover below.
- 1 to 2 years: around 350ml (12oz) a day.
- 2 to 3 years: similarly around 350ml; it doesn't change dramatically after 12 months, though more of it can come from food sources like cheese and yoghurt as meals become better established.
Whichever age your toddler is, 350ml is the number to keep in mind as their total daily fluid from milk sources, not a figure you need to hit exactly through a beaker at the table.
From 12 months, whole or semi-skimmed cows' milk is suitable to give toddlers. Many parents choose to continue with whole milk for the extra fat and fat-soluble vitamins, but it's genuinely personal choice.
Does milk fill toddlers up so they eat less food?
In short, yes, past a certain point. Milk is calorie-dense, so a toddler drinking well over 500 to 600ml a day is often the same toddler pushing dinner away and living on small mouthfuls at mealtimes. A full tummy of milk, which can be drunk quickly and easily, leaves less room and less appetite for the iron-rich foods, meat, pulses and dark leafy veg, that a growing toddler actually needs. Low iron in the second year is common enough that the NHS flags it as a real risk, and excess milk intake is one of the most fixable causes.
If you're not sure whether this is happening at home, a three-day food and drink diary usually tells you fast: if milk keeps turning up between meals as well as at them, think splashed over cereal, plus a cup with lunch and another at bedtime, that's your answer. A beef-based dinner like our Pasta Bolognese, made with grass-fed British beef mince, is one easy way to get an iron source back on the plate without a fight, and iron is worth reading up on if you want the fuller picture. This is one of the questions I get asked most, so if it's on your mind, have a look at more of your foodie questions answered by our Children's Dietitian.
What if my toddler won't drink milk at all?
This is the flip side of the same worry, and it isn't the crisis it can feel like. Provided calcium and vitamin D needs are met through food, cheese, yoghurt and other calcium-set foods count towards the same daily allowance, so a toddler who refuses a cup of milk outright isn't automatically falling short (see the milk-portion table below). If you're relying entirely on food sources and still unsure, a health visitor or GP can check this properly and advise on a supplement if one's needed.
How much water does a toddler need each day?
Offer water freely alongside meals and snacks, roughly 6 to 8 small cups a day from age 1, more in hot weather or after a lot of running around. Water is the drink to reach for between milk and meals: it doesn't touch appetite the way milk does, and it's kinder to teeth. Try to offer water through the day and a smaller amount alongside the meal itself, not a full cup five minutes before you sit down.
How much should a toddler drink in total each day?
Put milk and water together and a rough daily picture for a 1 to 3 year old looks like this:
| Drink | Roughly how much |
|---|---|
| Milk (or dairy-food equivalent) | ~350ml (12oz) |
| Water | 6 to 8 small cups |
| Juice, if offered at all | up to 150ml, well diluted |
That's the whole day in one place, rather than adding the sections up yourself. None of these are hard ceilings for every toddler, but they're the range I'd expect a typical day to fall into.
When should a toddler move from a bottle to a cup?
I tell parents to have milk fully out of a bottle by 18 months, with an open or free-flow cup introduced well before that, ideally from weaning age. If you're only just starting to think about moving your toddler off milk from a bottle, our 10 tips to support your weaning journey covers the wider transition.
Many parents find making the swap gradually rather than all at once helpful; for example, drop one bottle feed a week, starting with the one your toddler seems least attached to (usually not bedtime first). By 18 months, the bottle should be gone entirely.
What actually counts as a milk portion?
Milk doesn't have to arrive in liquid form. Cheese, yoghurt and other calcium-set foods all count towards that daily allowance, which is useful on the days your toddler won't touch a cup.
| Milk-equivalent portion | Roughly counts as |
|---|---|
| 100ml whole milk | 100ml |
| Small pot of yoghurt (120g) | ~100ml |
| Matchbox-sized piece of cheese (30g) | ~200ml |
| Custard (100g) | ~100ml |
A dinner like our Cheesy Veg Pasta, made with whole milk and cheddar cheese, quietly ticks off a chunk of that allowance at the table. Our Broccoli Tots do something similar, made with real broccoli and cheddar cheese, so a toddler who won't drink much milk can still get close to their portion through food.
Is juice okay for toddlers, and how much?
A small amount of juice is fine, very occasionally rather than as a daily drink. If you offer juice, dilute it at least 1 part juice to 10 parts water, keep it to mealtimes only, and cap it at around 150ml a day.
Does milk at bedtime cause tooth decay?
Plain milk as part of the bedtime routine, followed by a teeth brush, is absolutely fine. What I'd steer you away from is a bottle left with your toddler to self-settle through the night, since that's prolonged contact between milk sugars and teeth with no brushing in between.
Should a toddler have milk with meals or between meals?
Either is fine on its own, but the trouble starts when milk becomes the answer every time your toddler asks for a drink. Offer it at breakfast, and again at one other point in the day such as a snack, and let water do the job the rest of the time, or work to a routine that keeps the day's total to around 350ml or less.
If you're ever unsure whether your toddler's drinks or diet are on track, your GP or health visitor can check growth and iron levels properly, and there's no such thing as a silly question to bring to them.
Getting drinks right isn't about being strict, it's one of those quiet wins that makes the rest of the day's eating easier. Small changes, made consistently, beat any perfect plan you abandon after a week.
