For a baby under 1, a shop-bought soya drink can be used in suitable weaning foods from around 6 months if soya is tolerated, but it must not replace breast milk or infant formula as the main drink, according to NHS weaning guidance. From age 1, the British Society for Allergy and Clinical Immunology says an unsweetened, fortified plant-based drink can be an alternative when it fits the child’s diet. A mild taste does not settle the questions of age, intended use, fortification or allergy.
The child’s age and the way you intend to use the drink change the buying decision more than a description of its flavour.
A soya drink added to porridge or a sauce is different from one served as the baby’s main drink. NHS Forth Valley says milk alternatives may be added to food from around 6 months, while breast milk or infant formula remains the main drink until age 1.
If the child can consume soya, check for an unsweetened, fortified drink and consider it alongside the rest of the child’s diet. The British Society for Allergy and Clinical Immunology identifies calcium, iodine and several vitamins as relevant fortification checks; individual pack warnings still matter.
A dairy-free soya drink still contains soya. NHS allergy guidance notes that some children with cow’s-milk-protein allergy may not tolerate soya, so a planned milk substitution should follow the child’s clinical or dietetic advice.
Start with the child’s age and whether the drink will go into food or be served as a drink. Only then compare cartons for ingredients, fortification and flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Age and use | For a baby under 1, distinguish adding a milk alternative to suitable food from replacing the main drink. NHS Forth Valley places food use from around 6 months and main-drink use of shop-bought alternatives after age 1. | I’m mixing a drink into porridge or a sauce, not replacing my baby’s usual milk. If I need a main drink before age 1, a standard soya carton is not the substitute to choose. |
| Sugars and fortification | For a child aged 1+, the British Society for Allergy and Clinical Immunology advises an unsweetened, fortified plant drink. Check the ‘of which sugars’ figure and look for at least 120 mg calcium per 100 ml, iodine, riboflavin, vitamin B12 and vitamin D; read the product’s age warning too. | After age 1, I want to compare the actual nutrition panels rather than assume that every unsweetened or plant-based carton has the same fortification. |
| Mild flavour | Check whether the flavour description comes from the manufacturer and whether the particular drink is unsweetened. Treat taste wording as separate from feeding suitability. | A less pronounced soya taste could suit the foods I’m preparing, but I would choose a carton only after checking its age-appropriate use and ingredients. |
| Allergens | Read the current ingredients and allergen declaration for soya and any other declared allergens. With diagnosed or suspected allergy, check the child’s clinical plan before changing milk sources. | Dairy-free matters to me, but it does not tell me whether my child can have soya. |
Neither description changes the role of breast milk or infant formula for a baby under 1. NHS weaning guidance distinguishes a milk alternative added to food from the baby’s main drink.
If the baby is under 1, keep breast milk or the appropriate infant formula as the main drink. From around 6 months, use a tolerated milk alternative only in suitable weaning foods.
Plant-based drinks vary in sugars and fortification. For children aged 1+, the British Society for Allergy and Clinical Immunology’s guidance concerns unsweetened, fortified drinks, not every product labelled soya.
Compare the ‘of which sugars’ figure, calcium per 100 ml, iodine and listed vitamins. Check for sweeteners and read any product-specific age warning.
Soya is itself an allergen. NHS allergy guidance notes that some children with cow’s-milk-protein allergy may not tolerate it.
Read the current allergen declaration. For a child with a diagnosed or suspected allergy or a previous reaction, follow their clinician’s or dietitian’s plan before substituting soya.
General guidance for children aged 1+ does not override a restriction on a particular product. Waitrose & Partners lists its Essential Unsweetened Soya Drink as unsuitable for children under 2.
Check the current pack’s age wording before buying for a child, even when its unsweetened and fortified description appears to match your other checks.
These examples help identify the formulations and label wording to compare; a reference to one drink does not establish the suitability of every product from that brand.
UK retail listings describe Alpro Soya No Sugars as a soya drink with added calcium, iodine and vitamins B2, B12 and D2. The ‘mild, mellow’ taste description is the manufacturer’s wording.
NHS North West Knowledge Now’s February 2026 resource includes Tesco Soya Drink Unsweetened among examples of soya-based drinks for children aged 1+ with cow’s-milk-protein allergy.
NHS North West Knowledge Now’s February 2026 resource names Sainsbury’s Unsweetened Soya Drink (chilled) as an example for its defined age-1+ cow’s-milk-protein-allergy context.
NHS North West Knowledge Now’s February 2026 resource includes M&S Plant Kitchen Unsweetened Soya Drink among its examples for children aged 1+ with cow’s-milk-protein allergy.
Waitrose & Partners lists Essential Unsweetened Soya Drink with 120 mg calcium per 100 ml and added iodine and vitamins D, B12 and B2.
This Alpro option is relevant when you want a mild-tasting, no-sugars soya drink for food preparation or are comparing drinks for an older child. Check the child’s age, soya tolerance and the current pack before deciding how to use it.

The product description calls the taste mild and mellow and lists cereal and cooking uses. It describes an 8 x 1L long-life pack with calcium and vitamins B2, B12 and D, and declares soya as an allergen. For a baby under 1, a suitable soya drink belongs in food rather than replacing breast milk or infant formula; if considering it as a drink from age 1, check the current carton for iodine, calcium per 100 ml and any age warning.
Not before age 1. NHS guidance says breast milk or infant formula remains the main drink while babies start solids; NHS Forth Valley says a milk alternative may instead be added to food from around 6 months.
Look for an unsweetened, fortified drink that the child can tolerate, and check its own age warning. The British Society for Allergy and Clinical Immunology advises checking for at least 120 mg calcium per 100 ml, plus iodine, riboflavin, vitamin B12 and vitamin D; formulations differ between cartons.
A soya drink can be dairy-free, but check the particular carton’s ingredients and allergen declaration rather than relying on the category name. Alpro Soya No Sugars is described as dairy-free in UK listings, but it contains soya, which is also an allergen.
No. ‘Mild’ describes flavour, not whether a drink is appropriate for the child’s age or intended use. Check whether it is going into food or being served as a main drink, then read the ingredients, nutrition panel, allergens and age wording.
Do not assume soya is suitable simply because it is dairy-free. NHS allergy guidance notes that some children with cow’s-milk-protein allergy may also react to soya; follow the child’s clinical or dietetic plan before changing their milk source.
