Choose lactose-free cow’s milk only if lactose is the issue and your child can have cow’s-milk protein: lactose-free milk still contains dairy. If cow’s milk must be avoided because of allergy, choose a dairy-free alternative that fits your child’s age and allergy plan. For regular use, check the drink’s calcium, iodine, energy and protein information as well as whether its label permits use as a main milk drink.
If a toddler can have cow’s-milk protein but needs to avoid lactose, lactose-free dairy milk may be an option for dinner, cereal or cooking. Nottinghamshire Area Prescribing Committee guidance notes that persistent primary lactose intolerance is rare in children under three; discuss an uncertain or continuing restriction with a healthcare professional.
Cow’s-milk-protein allergy calls for a genuinely dairy-free choice, not lactose-free cow’s milk. Check the alternative’s ingredients and other allergens, and follow the child’s allergy plan when choosing a regular replacement.
For a child aged one or over, an unsweetened calcium-fortified alternative can be considered as part of the diet, according to the NHS. Check the particular drink’s nutrition and age instructions rather than treating all plant-based drinks as interchangeable.
Decide first whether the child needs to avoid lactose or cow’s-milk protein. Then check the drink’s age instructions and its role at dinner or as a regular milk replacement.
Consider when: Lactose needs to be avoided but cow’s-milk protein can be consumed.
Limit: It still contains milk and is not an alternative for cow’s-milk-protein allergy.
Consider when: Cow’s milk must be avoided or the family chooses dairy-free food, subject to the child’s age and allergy plan.
Limit: Nutrients differ between drinks, and ingredients such as soya, nuts or oats may matter for other allergies.
| Priority | What to check | Your needs |
|---|---|---|
| Milk ingredients | Read the ingredients and allergen declaration. Lactose-free cow’s milk can still contain milk protein; check a dairy-free drink for its own allergens. | If cow’s-milk protein must be avoided, I need a dairy-free product, not just one labelled lactose-free. |
| Age and use | Check the child’s age and whether the label permits the drink as a main milk drink. The NHS says breast milk or first infant formula is the suitable main milk before 12 months; a product may set stricter limits later. | A drink used in a sauce is different from one my child relies on every day, so I need to check the intended use. |
| Nutrition | For a regular dairy-free replacement, compare calcium fortification, iodine, energy and protein on the carton. Kingston and Richmond NHS Foundation Trust advises looking for 120mg calcium per 100ml when dairy is excluded. | If dairy is off the menu, I want to compare what the chosen drink contributes rather than choosing by flavour alone. |
| Current label | Read the carton’s ingredients, highlighted allergens and age instructions, including on repeat purchases. | For nursery or a shared dinner, I need to check the actual carton before serving or sending it. |
Lactose-free dairy products can contain cow’s-milk protein. Arla LactoFREE Whole Milk, for example, declares milk as an allergen.
For cow’s-milk-protein allergy, follow the child’s allergy plan and choose an appropriate dairy-free product instead.
The UK government’s SACN and COT assessment says the nutrient content of plant-based drinks varies considerably, which matters when a drink regularly replaces dairy.
Compare the carton’s calcium fortification, iodine, energy and protein information alongside its ingredients.
A drink permitted in food or from age one is not necessarily suitable as a main milk drink. Waitrose says its Essential Unsweetened Oat Drink is not suitable as a main milk drink for children under three.
Check both the child’s age and the intended use against the particular product label.
A previous purchase or online listing may not reflect the carton being served, particularly where an allergen must be avoided.
Read the current ingredients and allergen declaration each time, including before sending a drink to nursery.
These examples show why a lactose-free dairy label and a dairy-free drink label answer different needs; check the individual product before use.
Its whole milk drink is a lactose-free dairy option made with whole milk and lactase enzyme, according to Arla.
Tesco’s listing for Arla LactoFREE Whole Milk identifies it as a lactose-free whole filtered milk drink.
Sainsbury’s lists an Arla LactoFREE whole milk drink in a 2L format.
M&S Made Without Lactose Whole Milk is a lactose-free cow’s-milk product.
Waitrose Essential Unsweetened Oat Drink is a dairy-free example fortified with calcium, iodine and listed vitamins.
These soya and almond drinks are options to consider for a dairy-free toddler dinner when their ingredients fit the child’s allergy plan. Check each carton’s age guidance and nutrition before using it regularly as a milk replacement.

For a dairy-free dinner where soya is suitable, this is a no-sugars, long-life soya drink supplied as 8 x 1L. Check the current allergen label, age guidance, calcium and iodine information before using it regularly as a milk replacement.

For a dairy-free dinner where almond is suitable, this is a no-sugars, long-life almond drink supplied as 8 x 1L. Check the current nut allergen label, age guidance and nutrition information, particularly if it will regularly replace dairy.
No. Lactose-free cow’s milk can still contain milk protein: Arla lists whole milk in its LactoFREE Whole Milk ingredients, and M&S says its lactose-free products are unsuitable for dairy allergy. Follow the child’s allergy plan if cow’s milk must be avoided.
From age one, the NHS says unsweetened calcium-fortified milk alternatives can be given as part of a balanced diet. Check the particular drink’s age instructions and whether it is suitable as a main milk drink; before 12 months, breast milk or first infant formula remains the suitable main milk.
Check the age statement, allergens, calcium fortification, iodine, energy and protein, especially if the drink will regularly replace dairy. Kingston and Richmond NHS Foundation Trust advises looking for 120mg calcium per 100ml when dairy is excluded; also check whether the chosen product permits use as a main milk drink.
Read the current carton’s ingredients and allergen declaration, even if you have bought the product before. GOV.UK allergen guidance identifies milk among the allergens for which food businesses must provide information when it is an ingredient; a lactose-free label does not mean milk-free.
