Toddler milk market surges amid concerns over marketing claims and nutrition

The booming sales of toddler milk, driven more by marketing than nutritional need, raise questions about health, costs, and ongoing industry influence on parent choices worldwide.

Toddler milk has become a lucrative corner of the global formula market, even as public health experts question whether it is needed at all. The product, aimed at children aged one to three, is now a routine part of feeding in some countries; in Australia, more than a third of toddlers are said to drink it, while worldwide it accounts for close to half of formula milk sales. Researchers and clinicians argue that this growth has been driven less by nutrition than by marketing, which presents the drinks as a smart bridge between infancy and family foods.

The appeal lies in the promises on the tin. Toddler milks are typically sold as supporting growth, brain development and immunity, and as a fix for fussy eating. Yet according to nutrition experts writing in The Conversation, the products are usually ultra-processed, made with skim milk powder, vegetable oils, sugars and emulsifiers, and then fortified with added vitamins and minerals. They are often lower in protein and calcium than plain cow’s milk and can contain as much sugar as a soft drink in a single serving, depending on the brand. Health authorities including the World Health Organisation and Australia’s National Health and Medical Research Council do not recommend them for healthy toddlers who already eat a varied diet.

That gap between marketing and evidence has troubled researchers for years. A 2022 commentary from the World Health Organisation warned that commercial milk formula advertising can undermine breastfeeding and exploit parents’ desire to do what is best for their children. Studies published in the International Breastfeeding Journal and Public Health Nutrition found that caregivers exposed to formula and toddler-milk advertising were more likely to believe product claims, even when those claims were not well supported. ProPublica reported in 2024 that the products are commonly promoted with language about intelligence and immune support, reinforcing the idea that they are a developmental necessity rather than an optional beverage.

Critics also say toddler milk was never simply a response to nutritional need. It emerged, they argue, as a way for formula manufacturers to keep marketing after restrictions on infant formula advertising. By packaging toddler products as the next stage after infant formula, companies can build brand loyalty and create what public health campaigners describe as cross-promotion: once families trust a toddler milk brand, they may be more likely to buy the company’s infant formula too. The labels are often designed to look alike, helping to preserve recognition across product lines.

The financial cost is another part of the problem. Toddler milk can be four or five times more expensive than regular cow’s milk, and so-called premium versions cost even more. In a period of rising household pressures, that leaves parents vulnerable to spending heavily on a product they may believe is essential. The broader concern, voiced by the WHO and by child health researchers, is that toddlers should be encouraged to eat ordinary foods, alongside breastmilk where possible and, if appropriate, cow’s milk or another suitable milk alternative. For families worried about eating habits or nutrition, clinicians say the answer is not a branded drink, but professional advice and a closer look at the child’s overall diet.
