Transitioning from Formula to Cow's Milk: What I Wish I'd Known

Turning one isn't just about cake and presents. It's also time for a major change in your baby's diet: saying goodbye to formula and hello to cow's milk.
To ensure I handled this important transition correctly, I dedicated significant time to researching NHS guidelines, consulting our paediatrician, and comparing various milk options. There was a lot to consider, from nutritional content to additives and vitamins.
In this article, I'll share everything I learned about switching from formula to whole milk. Hopefully, this will help other parents who are about to go through the same stage with their little one!
When's the Best Time to Switch to Cow's Milk?
According to the NHS, babies can start drinking whole cow's milk from 12 months old. Before this, their digestive system isn't mature enough to handle it as a main drink, and formula or breast milk provides the essential nutrients they need.
Why Not Before 12 Months?
- Lack of key nutrients: Cow's milk doesn't provide enough iron, vitamin E, or essential fatty acids.
- Difficult to digest: It contains higher levels of protein and minerals, which can put extra strain on an infant's kidneys.
- Risk of anaemia: Drinking too much cow's milk before 12 months can interfere with iron absorption.
How Can I Transition to Whole Milk Smoothly?
Some parents prefer to switch all at once, while others take a gradual approach. If you choose to transition slowly, you could start by mixing prepared formula with cow's milk and gradually increase the amount over time.
For us, the transition was smoother than expected. We switched to whole milk once she turned one, but in hindsight, she was already used to the taste. We had been giving her whole milk in foods like porridge, and she was already eating other dairy products such as yoghurt.
How Many Calories Does Whole Milk Have Compared to Formula?
One of my biggest concerns when switching from formula to cow’s milk was whether my baby would be getting enough calories.
What Kind of Milk Is Best for a 1-Year-Old?
When switching from formula to cow's milk, I wanted to make sure I was choosing the best option for my little one. We ultimately chose organic whole milk.
The NHS recommends whole milk (full-fat) for children aged 1 to 2 years because they need the extra fat for brain development and energy.
How Much Milk Should They Be Drinking?
The NHS recommends giving at least 350ml (12oz) of milk per day for toddlers aged 1 to 2 years. This can come from whole cow's milk, breast milk, or a combination of both.
Other Things to Consider When Switching to Cow's Milk
One important consideration is how your toddler drinks their milk. The NHS recommends moving from bottles to cups at 12 months to support oral development and prevent tooth decay.
It's also important to watch for signs of cow's milk allergy or lactose intolerance, which can include digestive issues, skin reactions like eczema, or respiratory symptoms.
Final Thoughts
Switching to whole milk has made life a lot easier for us. Formula is expensive, so not having to buy it anymore has been a huge relief.
If you're in the process of making the switch, know that every child adjusts differently. Some take to whole milk straight away, while others need a bit more time.
