When can a toddler drink cow's milk? Age, amounts and how to switch

You can let your toddler drink cow's milk once they've turned one. HealthHub says younger babies can't digest it as easily as breast milk or formula. From then, plain full cream milk can replace formula at about 400 to 500 ml a day, HealthHub suggests, and breastfeeding can carry on. Here's how to switch, and when to see a doctor.

How to switch from formula to fresh milk, step by step

1. Ask your doctor before you start the switch at one. HealthHub advises it because some babies have a milk allergy or a special diet.
2. Wait until your child has turned one before you switch. HealthHub says switching too early can lead to iron-deficiency anaemia in some babies.
3. Buy plain full cream milk from the chiller, the shelf or a tin. HealthHub calls it a convenient source of calcium and protein.
4. Mix it into breast milk or prepared formula to start. HealthHub suggests one part full cream milk to three parts of the usual milk, then a bigger share bit by bit.
5. Cook with milk so your child gets used to the taste. HealthHub suggests oatmeal made with milk, or milk added to a smoothie.
6. Serve milk in an open cup, then move on to a straw. HealthHub's Parent Hub gives this order and says to skip sippy cups.
7. Give milk with meals and snacks rather than all day long. HealthHub warns that too much milk can leave a child too full for food.
8. Phase out the milk bottle by age one to protect teeth, as HealthHub advises. Brush your child's teeth after the last milk feed of the day.
9. Tell your helper, the grandparents and the infant care centre the plan, so that everyone mixes the milk the same way and serves it in the same kind of cup.
10. Keep breastfeeding if you both want to. HealthHub says it can go on until your child is 2 or older.

How much milk does a toddler need?

HealthHub says a toddler should drink 400 to 500 ml of milk a day, and it adds that much more than 500 ml may be a sign your child isn't eating enough food. Another HealthHub page puts the daily amount at about 2 to 3 cups. After age one, most calories should come from solid food, HealthHub says, so think of milk as a drink with the meal.

SingHealth's HealthXchange says most children need only 500 ml of milk a day to meet their calcium needs. For babies under one, use the milk feeding calculator for breast milk and formula. Our starting solids guide shows how food fits in before the first birthday. For water, see how much water babies and toddlers need.

Full cream milk for toddlers, or low fat?

Keep your child on full cream milk until their second birthday. HealthHub says children aged 12 to 24 months need it for growth and brain development, which low-fat milk can't support. After two, you can move to low-fat milk if your child is eating well. Skimmed or non-fat milk waits until five, as HealthHub says it lacks the calories and nutrients younger children need.

If obesity, heart disease or high cholesterol runs in the family, HealthHub suggests asking your doctor whether low-fat milk could start a little earlier than two.

You may see a Nutri-Grade C on the full cream carton. HealthHub says the C reflects its saturated fat compared with low-fat milk, and that full cream milk still meets a 1 to 2 year old's needs for fat, protein, vitamins and minerals.

Fresh, UHT and powdered full cream milk all count. With powder, check the tin says full cream, not filled milk or formula. HealthHub's Parent Hub says filled milk, made with non-milk fats such as palm oil, is unsuitable for toddlers. It also rules out the condensed and evaporated milk used in kopi and teh. Both are high in sugar and saturated fat, it says. Flavoured milk is out as well, because its added sugar can cause tooth decay.

Do toddlers need growing-up milk?

HealthHub's advice for a child past 12 months who isn't breastfed is plain full cream milk with a balanced diet. It says growing-up or fortified formula may be more energy-dense than full cream milk. That can take the edge off your child's appetite for meals. The NHS says growing-up milks, toddler milks and other formula aren't needed after 12 months.

If your doctor has your child on a special formula, keep to it until they say otherwise. Our height guide looks at the growth claims on tins. The formula cost calculator shows what formula costs each month.

Too much milk: iron, appetite and constipation

A toddler who fills up on milk has less room for food. HealthHub says too much milk can leave your child too full for other food groups. HealthXchange adds that too much milk can push iron-rich foods out of the diet. Children under 5 are at higher risk of iron deficiency, it says, because they need more iron to grow. HealthHub notes that full cream milk has less iron than breast milk.

The Royal Children's Hospital Melbourne says children who drink large amounts of cow's milk each day may become constipated, and our toddler constipation guide covers what helps. If milk has been standing in for meals, the fussy eater guide and our guide to a balanced diet for toddlers show what to put on the plate instead.

Milk alternatives and raw milk

HealthHub lists cow's milk among the common food allergens. It says cow's milk protein allergy is often temporary, and children grow out of it after several years. Before choosing an alternative, HealthHub says to see a doctor if your child has a milk allergy, eats vegan or has a medical condition.

Its list includes unsweetened or reduced-sugar soy, almond or rice milk with added calcium. These usually have fewer calories and less protein than cow's milk. Soy-based milk has about half the energy of full-fat animal milk, the Parent Hub says. It suggests other energy-dense foods for children on soy-based or hydrolysed formula. One difference abroad: the NHS says children under 5 shouldn't have rice drinks because of their arsenic levels.

Some toddlers won't drink milk at all, whatever you mix it with. HealthHub suggests yoghurt, cheese and other high-calcium foods to meet their calcium needs. If milk seems to upset your child's tummy, see our lactose intolerance guide. For allergens, read allergy-friendly eating in Singapore.

For safety, give your child pasteurised milk only. SFA says raw liquid milk isn't allowed to be sold in Singapore. It also says infants and children should avoid raw milk and products made with it. Some raw-milk cheeses are sold here, so check the label or ask the seller, as SFA suggests.

When to see a doctor

For most milk worries, start with your GP or polyclinic. KKH says they're the place for non-emergency problems. For urgent care, KKH says to go to the nearest children's emergency department, such as KKH or NUH Children's Emergency. If it's an emergency, such as trouble breathing, call 995 straight away.

• Call 995 if your child has trouble breathing or wheezes after milk or any food. HealthHub lists this as a reason to call an ambulance.
• Call 995 for a swollen tongue, a hoarse voice, a persistent cough or trouble swallowing. The same goes if your child turns suddenly sleepy or pale (HealthHub).
• See a doctor if your child's face, eyes or lips swell after milk. Vomiting or a widespread rash are reasons too, says HealthHub.
• See a doctor if your child gains weight poorly or keeps getting infections. HealthXchange links both with iron-deficiency anaemia in children.
• Ask your doctor or a dietitian if your child refuses milk, yoghurt and cheese. HealthHub says a paediatrician can check their diet has enough protein, vitamins and minerals.

Frequently asked questions

When can my toddler drink cow's milk instead of formula?

Your toddler can switch from the first birthday. Check with your doctor first if your child has an allergy or a special diet, HealthHub says. Mixing it with formula at first helps your child get used to the taste.

How much milk should a toddler drink a day?

HealthHub suggests 400 to 500 ml a day, or about 2 to 3 cups. Much more than 500 ml can mean your child isn't eating enough. Serve it with meals and snacks so food stays the main event.

Is full cream milk for toddlers better than low-fat?

Up to age two, full cream milk is the better choice. HealthHub says children aged 12 to 24 months need it for growth and brain development. After two, low-fat milk is fine if your child is eating well.

Does my toddler need growing-up milk?

The NHS says growing-up and toddler milks aren't needed once a baby is 12 months old. HealthHub says growing-up milk may be more energy-dense than full cream milk and can crowd out appetite for meals. If your doctor prescribed a special formula, keep to it until they say otherwise.

What if my toddler refuses fresh milk after switching from formula?

Slow down and keep mixing it with formula, then raise the share of fresh milk bit by bit. HealthHub also suggests cooking oatmeal with milk or adding it to a smoothie. If your child still says no, yoghurt, cheese and other high-calcium foods can meet their calcium needs.

Can I keep breastfeeding after my toddler starts cow's milk?

Yes, you can keep breastfeeding for as long as you both want. HealthHub calls breastfeeding the best option and notes the WHO recommends it until age 2 and older. You can breastfeed instead of giving full cream milk, or do both. When you're ready to stop, our guide on how to wean from breastfeeding takes you through it.
