Baby formula, also known as infant formula, first milk, or bottle-feeding milk, is a safe, nutritionally regulated alternative to breast milk.
What is Baby Formula?
Baby formula is a specially manufactured food created to meet the nutritional needs of infants from birth to 12 months. All infant formula sold in the UK is strictly regulated to provide appropriate levels of protein, fats, carbohydrates, vitamins and minerals necessary for healthy growth.
First infant formula is the recommended alternative to breast milk during the early months and is suitable for most babies throughout their first year.
Benefits and Features of the Welzo Baby Formula Collection

Why is Baby Formula Important?
Baby formula provides essential nutrition when breastfeeding is not possible or not chosen. It contains the energy, fats, proteins, vitamins and minerals required for early physical and cognitive development.
Formula feeding also offers families flexibility, predictable feeding volumes and convenience, ensuring babies receive complete nutrition during their first 12 months.
How to Use Baby Formula
- Sterilise bottles, teats and feeding equipment until your baby is 12 months old.
- Use freshly boiled water cooled to at least 70°C before mixing powdered formula, as this helps eliminate harmful bacteria.
- Prepare feeds fresh, ideally just before each feed, rather than in advance.
- Discard leftover formula after feeding, as bacteria multiply quickly once a bottle has been used.
These steps help reduce the risk of contamination and ensure your baby receives formula safely.
