For a baby under 12 months, an ordinary soya drink should not replace breast milk or first infant formula as the main milk feed, according to NHS guidance. From around six months, a fortified plant-based drink can be used in cooking while milk feeds continue. For a child aged one or over, check that any soya drink is unsweetened and fortified, follow its age guidance, and remember that dairy-free does not mean soya-free.
The child’s age and whether soya is suitable for them matter more than a dairy-free claim on the front of the carton.
From around six months, you may be considering a plant-based drink for porridge, sauces or family meals. NHS guidance keeps breast milk or first infant formula in its separate role as the baby’s main milk feed during the first year.
For a child aged one or over, compare unsweetened products, their fortification and the age instructions on the exact carton. A drink suitable for cooking is not necessarily labelled as a suitable main milk drink for every toddler.
A dairy-free soya drink still contains soya. When soya is new to a baby, NHS guidance advises introducing foods that can trigger allergy one at a time so that a reaction can be spotted. Seek individual advice if the child has a diagnosed allergy or has reacted to a food.
Start with the drink’s intended use and the child’s age, then read the allergen, nutrition and age information on the current carton.
| Priority | What to check | Your needs |
|---|---|---|
| Milk feeds and cooking | Check whether the drink is intended for cooking or as a main drink. NHS guidance says first infant formula is the suitable alternative to breast milk during the first 12 months; NHS-linked feeding guidance allows plant-based drinks in cooking from around six months, not as the main milk drink before age one. | I’m adding a little dairy-free drink to family food, not replacing my baby’s milk feeds. |
| Age instructions | Read the exact carton’s child-age and intended-use wording. Sainsbury’s states that its Unsweetened Long Life Soya Drink can be used as part of a balanced diet from age one but is not suitable as a main milk-drink alternative for children under two. | My child is over one, and I need to know whether this particular drink is appropriate for the way I plan to use it. |
| Ingredients and allergy | Check the ingredients and allergen statement for soya. NHS guidance advises introducing foods that can trigger allergy one at a time from around six months so that a reaction can be identified. | Dairy-free alone is not enough for my family if soya is an allergen for my child. |
| Sugars and fortification | For children aged one or over using a plant-based drink, compare unsweetened choices and read the nutrition and ingredients labels for calcium, iodine, vitamin D, vitamin B12 and riboflavin. The British Society for Allergy and Clinical Immunology recommends fortified, unsweetened plant-based drinks; the UK’s SACN and COT assessment notes that nutrient content varies considerably between products. | I want to compare what the carton actually contains rather than assume all unsweetened soya drinks have the same added nutrients. |
An ordinary plant-based drink does not take the place of breast milk or first infant formula as the main milk feed in the first year, according to NHS guidance.
From around six months, keep a fortified plant-based drink to cooking uses while milk feeds continue. If a baby needs a different feeding plan because of an allergy, discuss it with a GP, health visitor or dietitian.
The UK’s SACN and COT assessment says the nutrient content of plant-based drinks varies considerably. A dairy-free claim does not tell you the drink’s calcium, iodine or vitamin content.
For a child aged one or over, compare unsweetened products and check the current carton for its listed fortification and nutrition values.
Soya can trigger an allergic reaction even though a soya drink contains no dairy ingredients. A milk-allergy feeding plan does not, by itself, establish that soya is suitable.
Read the allergen statement. If soya is new to your baby, follow NHS advice to introduce foods that can trigger allergy one at a time; get individual advice if your child has a diagnosed allergy or a suspected reaction.
General guidance for children aged one or over does not override instructions for a particular drink. For example, Sainsbury’s says its Unsweetened Long Life Soya Drink is not suitable as a main milk-drink alternative for children under two.
Check the exact product’s age and intended-use statement before choosing it as a toddler’s regular drink.
These product-line examples show why the current carton matters; a brand name alone does not establish a drink’s ingredients, fortification or suitability for a child.
Sainsbury’s lists Alpro Soya No Sugars as a long-life soya drink with added calcium, iodine and vitamins B2, B12 and D2.
Sainsbury’s Unsweetened Long Life Soya Drink is listed as fortified with calcium, iodine, vitamin D and vitamin B12.
Waitrose describes its Essential Unsweetened Soya Drink as fortified with calcium, iodine and vitamins D, B12 and B2.
M&S lists an unsweetened soya drink fortified with calcium, iodine, vitamin D and vitamin B12.
The long-life soya drink below is an option to examine for dairy-free cooking and, where age-appropriate, label comparison. Its pack details do not make it an infant milk replacement.

This dairy-free soya drink is listed for uses including cooking, but it must not replace breast milk or first infant formula as a baby’s main milk feed.
The listing describes a UHT pack of 8 x 1L, states 0.0g sugars per 100ml and lists calcium and vitamins B2, B12 and D. It contains soya. For a child aged one or over, check the current carton for child-age guidance, iodine and the amounts of added nutrients before choosing how to use it.
No. NHS guidance says first infant formula is the suitable alternative to breast milk during the first 12 months. An ordinary soya drink can have a different role in cooking from around six months, but should not become the main milk drink.
A fortified plant-based drink can be used in cooking from around six months while breast milk or first infant formula remains the main milk feed, according to NHS-linked feeding guidance. Check the ingredients for soya, particularly if it is new to your baby.
Compare unsweetened, fortified drinks and check the label for calcium, iodine, vitamin D, vitamin B12 and riboflavin, alongside its child-age instructions. The British Society for Allergy and Clinical Immunology recommends fortified, unsweetened plant-based drinks for children aged one or over; that general guidance does not replace a particular carton’s intended-use wording.
Not automatically: a soya drink still contains soya, which can also trigger allergy. If a baby needs a milk-feeding alternative because of a diagnosed or suspected allergy, discuss the feeding plan with a GP, health visitor or dietitian rather than substituting an ordinary supermarket drink.
From around six months, NHS guidance advises introducing foods that can trigger allergy one at a time so that you can spot a reaction. If your baby has a diagnosed allergy or has reacted to a food, seek individual advice before offering soya.
