Who needs to make this choice?

Parents weaning a baby under 12 months

The main drink remains breast milk or suitable infant formula. NHS guidance distinguishes that role from using other milks in food during weaning.

Households choosing vegan food

Check whether a drink is genuinely plant-based: lactose-free cow’s milk remains dairy. The Vegan Society’s Vegan Trademark standards exclude animal-derived ingredients.

Parents concerned about a reaction to milk

Healthier Together NHS distinguishes difficulty digesting lactose from allergy to cow’s-milk proteins. A baby with suspected allergy needs clinical advice rather than a switch to ordinary lactose-free milk.

What should you check first?

Start with the baby’s age and the drink’s intended use, then check whether the requirement is vegan food, lactose reduction or avoidance of milk protein.

Priority What to check Your needs
Main drink and age For babies under 12 months, keep breast milk or suitable infant formula as the main drink. The NHS says cow’s milk can become a main drink from 12 months. I’m choosing something to put in food, not a replacement for my baby’s milk feeds.
Use in food Frimley Health NHS Foundation Trust says carton plant drinks may be used for cooking or mixed into food from six months unless a dietitian advises otherwise. Check the product’s ingredients and pack directions. I want a plant drink for a weaning recipe while continuing my baby’s usual milk feeds.
Vegan ingredients Read the ingredients rather than relying on “lactose-free”. Tesco and M&S identify their lactose-free drinks as cow’s milk; the Vegan Society’s trademark standards exclude animal-derived ingredients. Our household avoids animal ingredients, so lactose-free dairy milk does not meet that requirement.
Milk allergy Check the current ingredients, allergen declaration and precautionary wording. Healthier Together NHS identifies cow’s-milk allergy as a reaction to milk proteins, which lactose-free dairy milk still contains. If my baby may have a milk allergy, I need clinical advice on feeding rather than assuming a lactose-free or vegan label settles the question.
Plant-drink label Compare the current ingredients and stated fortification if those details matter to your choice. The Vegan Society cautions that vegan claims do not automatically establish allergy safety. I need to check what this particular plant drink contains, especially if my child has a diagnosed food allergy.

Mistakes to avoid

  • Assuming lactose-free means dairy-free

    Lactose-free cow’s milk still contains milk proteins. Arla LactoFREE’s product information specifically warns that its milk is unsuitable for people with milk allergy.

    Read the ingredients and allergen statement. If cow’s-milk allergy is suspected, follow clinical feeding advice.

  • Replacing infant formula with a carton plant drink

    For a baby under 12 months, a plant drink used in food has a different role from breast milk or suitable infant formula as the main drink.

    Continue the baby’s appropriate milk feeds. Frimley Health NHS Foundation Trust allows carton plant drinks in cooking or mixed food from six months unless a dietitian advises otherwise.

  • Treating lactose intolerance and milk allergy as the same issue

    Healthier Together NHS explains that lactose intolerance concerns digestion of milk sugar, while cow’s-milk allergy concerns milk proteins. Switching between ordinary drinks based on symptoms alone may not address the right issue.

    Seek medical or dietetic advice if symptoms follow milk exposure, particularly before changing a baby’s main feeds.

  • Using a vegan logo as an allergy guarantee

    The Vegan Society says vegan claims should not automatically be considered safe for people with food allergies.

    For a diagnosed allergy, check the current pack’s allergen declaration and precautionary wording and follow the child’s clinical advice.

Brand and retailer references

These examples illustrate the difference between lactose-free dairy and plant-based drinks; a retailer’s range or category name does not determine whether an individual product is vegan or suitable for an allergy.

Arla LactoFREE

Arla LactoFREE is a lactose-free cow’s-milk range. Tesco and Waitrose product listings identify whole milk and lactase enzyme in its whole-milk drink.

  • A dairy option when lactose reduction, rather than a vegan product, is the requirement.
  • The product listings warn that it is not suitable for people with milk allergy.

Tesco

Tesco describes its own-label lactose-free skimmed drink as made from cow’s milk and lists milk and lactase enzyme among its ingredients.

  • The ingredient list makes its dairy identity clear.
  • It is not a vegan or cow’s-milk-free choice.

M&S

M&S describes whole and semi-skimmed lactose-free cow’s-milk options.

  • Its range distinguishes whole and semi-skimmed dairy options.
  • Lactose-free cow’s milk does not meet a vegan requirement.

Sainsbury's

A Sainsbury’s listing describes an Alpro soya drink as plant-based and lists added calcium, iodine and vitamins.

  • The listing identifies a plant-based alternative to dairy milk.
  • An ordinary soya drink is not infant formula and should not replace a baby’s main milk drink before 12 months.

Waitrose

Waitrose lists Arla LactoFREE whole milk drink with whole milk and lactase enzyme in its ingredients.

  • The product listing identifies what the lactose-free drink contains.
  • Its warning says the drink is unsuitable for people with milk allergy; its retail category does not make it dairy-free.

Questions about milk during weaning

Is lactose-free dairy milk vegan?

No. Lactose-free dairy milk remains cow’s milk: Tesco, Arla and M&S identify their lactose-free products as dairy, while the Vegan Society’s Vegan Trademark standards exclude animal-derived ingredients.

Can milk or a plant drink replace my baby’s main milk feed during weaning?

Not before 12 months. NHS guidance identifies first infant formula as the suitable alternative to breast milk during the first year and says cow’s milk can become a main drink from 12 months. Frimley Health NHS Foundation Trust says carton plant drinks may be used in cooking or mixed into food from six months unless a dietitian advises otherwise, while breast milk or appropriate infant formula remains the main drink.

Is lactose-free cow’s milk suitable for a baby with cow’s-milk allergy?

Do not use lactose-free cow’s milk as an allergy substitute: it still contains the milk proteins involved in cow’s-milk allergy. Healthier Together NHS distinguishes this allergy from lactose intolerance, and Arla warns that its LactoFREE milk is unsuitable for people with milk allergy. Seek advice from a GP, health visitor or dietitian if allergy is suspected.

Does a vegan label mean a drink is safe for milk allergy?

No. The Vegan Society says vegan claims should not automatically be considered safe for people with food allergies. Check the current pack’s ingredients, allergen declaration and precautionary wording, and follow the child’s allergy advice.
