Growing-Up Milk: A Simple Way to Fill the Nutrition Gaps of Toddlers
Between the bottle years and the family table, toddlers go through a nutritional transition that's easy to underestimate. Here's what the evidence says about growing-up milk (GUM) and the role it can play in filling the gaps that often show up at this age
Ages 1 to 3: a critical nutritional transition.
Breastfeeding is recommended up to two years and beyond, alongside a progressively diversified diet. For families who have stopped breastfeeding, or are looking to round out an already varied diet, growing-up milk is one option among several formulated for children in this age group.
Around 12 months, babies start moving from milk feeds toward the food the rest of the family eats. It's a big milestone, but it's also when things tend to drift: processed foods, snacking between meals, and portions sized more for an adult than a toddler often add up to too much salt and protein, and too little of the essential fats, vitamins, and minerals a growing child needs.
A toddler's nutritional needs simply aren't the same as an adult's, or even a younger baby's. They're specific to this stage of life, and getting them right matters for how a child grows and develops.
Growing-up milk is one option that has been developed to help address this gap, as part of a varied, balanced diet. It is not a substitute for breastfeeding and is not intended as a sole source of nutrition.

An intake of approximately 500 ml of growing-up milk per day, the equivalent of two servings, has been shown to limit excess salt and protein consumption while reducing the risk of insufficient iron, essential fatty acid, and vitamin C and D intake.

Omega-3 and omega-6: essential to neurological development
Pound for pound, toddlers need 3 to 5 times more dietary fat than adults do — fat can make up 40% of their daily energy. Omega-3 and omega-6 fatty acids matter a lot here, since they're central to brain development, but they're also among the nutrients kids tend to fall short on, largely because plain cow's milk barely contains either.
A study in Mexico, published in the journal Nutrients, found a clear improvement in children's fatty-acid levels among those drinking a formula enriched with omega-3 and omega-6. The French Nutri-Bébé survey (2013) tells a similar story: toddlers drinking growing-up milk had 77% more omega-6 and 71% more omega-3 in their diets than those who didn't.
Moderating protein intake: a long-term health consideration
The World Health Organization (WHO) recommends around 11.4 g of protein a day for children aged 1 to 3. In practice, many toddlers get up to four times that. That excess isn't harmless — a report from the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee on Nutrition links it to a higher risk of becoming overweight later in life.
Swapping cow's milk for growing-up milk, as part of an otherwise varied diet, is estimated to cut daily protein intake by around 25 g on average, according to Nutri-Bébé survey data.
Iron: a frequently underestimated requirement
Not getting enough iron in early childhood can leave lasting marks on memory and learning, and sometimes even on vision or hearing. The French CARMA study found that children who regularly drank iron-fortified growing-up milk got close to half their daily iron needs from it, more reliably than occasional supplements manage.
Sodium intake: implications for renal and cardiovascular health
The WHO caps salt intake at 2 g a day for children between 18 months and 3 years, but toddlers this age typically eat about three times that. That's a lot for young kidneys to filter, and it's a known risk factor for high blood pressure later in life. The Nutri-Bébé survey found some good news here: children drinking growing-up milk had 19% lower sodium intake than those who didn't.
Comparative analysis with other milk types
A study of nearly 3,000 children in the Philippines looked at three groups: kids drinking growing-up milk, kids drinking other milks (cow's or otherwise), and kids drinking no milk at all. The growing-up-milk group came out ahead on iron, zinc, and vitamins C, D, E and B; and had the lowest overall risk of falling short on nutrients.
Conclusion
The everyday diet of a 1-to-3-year-old rarely covers everything they need on its own. Getting nutrition right at this age pays off, both in the short term and much further down the road. A fortified option like growing-up milk is one evidence-backed way to help close that everyday gap.
