A Parent’s Guide to Choosing the Best Infant Formula in NZ
Choosing the right infant formula can feel overwhelming, especially for first-time parents navigating feeding decisions for young infants. With many formulas on the shelf each specially formulated with different nutrients, proteins, and other ingredients it’s natural to want clear, practical guidance.
Many infant formulas in New Zealand are made with high-quality ingredients sourced from New Zealand farms, reflecting the country's reputation for purity, natural goodness, and sustainable practices. This means that when choosing a New Zealand infant formula, you can often trust the quality and traceability associated with Zealand's clean, green farming.
This introductory guide explains the different types of formula, how to read ingredient lists, and how to feed your baby safely.
Understanding Infant Formula and When It’s Used
Infant formula is a complete nutrition milk alternative designed to meet the nutritional requirements of infants from birth. While breastfeeding with breast milk/breastmilk is the gold standard and encouraged where possible, formula feeding is a suitable option for many families whether used exclusively or alongside breast milk feeds.
Infant formulas can be produced from various sources including cow, goat, and sheep or plant-based sources like soy milks. In New Zealand, most infant formulas are cow's milk-based, with specialised options such as soy, goat/sheep milk, lactose-free, and hydrolyzed formulas. All infant formulas sold in New Zealand are nutritionally complete and must meet strict standards set by Food Standards Australia New Zealand (FSANZ).
Formulas are carefully balanced to deliver essential nutrients such as proteins, fats, carbohydrates, vitamins, and minerals that support growth, brain development, and the immune system.
Breast Milk and Formula: How They Compare
Breast milk is the gold standard and naturally adapts to a baby’s age and needs, providing bioactive components that support health and digestion. Formula cannot replicate breastmilk, but it is designed to be nutritionally complete, providing consistent nourishment when breastfeeding isn’t possible or preferred.
Modern formulas include carefully selected amino acids, whey and casein protein ratios, and fatty acids such as DHA (often sourced from Schizochytrium sp) to support brain development.
Types of Infant Formula Explained
1) Cow’s Milk–Based Formula
Most standard formulas use cow's milk proteins that have been modified for infant digestion. Plain cow milk is not suitable for infants under one year old due to nutritional deficiencies and potential health risks. Standard cow's milk formula is the first choice for healthy, non-breastfed infants. Infants should not be fed plain cow, goat, or soy milks until one year of age due to their lack of essential nutrients. These typically include whey and casein, with lactose as the main carbohydrate. Many parents choose these formulas for their familiarity and balanced nutrient profile.
2) Goat Milk Formula
Goat milk formulas are increasingly popular. Goat milk has lower levels of αS1-casein than cow milk which may support gentler digestion, and goat milk is produced in a way similar to human milk resulting in higher levels of immunity and gut-supporting compounds.
Often praised for their natural goodness, they still provide calcium, phosphorus, iodine, and balanced proteins.
3) Lactose-Free Formulas
Designed for babies who struggle with lactose, these options replace lactose with alternative carbohydrates. They can be helpful when advised by a healthcare professional, especially if feeding discomfort persists.
4) Soy Milk Formula
Soy milk formula uses plant-based proteins and is free from lactose. It is sometimes chosen for dietary preferences or specific tolerances. Always seek professional healthcare advice before switching, as soy formulas differ in proteins and minerals.
Specialty Infant Formulas: Options for Unique Needs
Every baby is different, and some may need a little extra support when it comes to feeding. Specialty infant formulas are specially formulated to address unique dietary needs that standard formulas may not meet. These formulas are designed for babies who have specific conditions, such as lactose intolerance, allergies to certain proteins, or other medical concerns that affect digestion and comfort.
These specialty formulas are carefully balanced to ensure your baby receives complete nutrition, just like standard infant formula. If you think your baby might benefit from a specially formulated formula, it’s important to consult a healthcare professional for guidance. They can help you choose the right formula to support your baby’s feeding journey and overall wellbeing.
What to Look for on the Ingredients List
Understanding the label helps you compare formulas confidently:
- Proteins: Look for a balanced whey to casein ratio for easier digestion.
- Fats: A blend of vegetable oils; some parents prefer formulas without palm oil.
- Carbohydrates: Usually lactose; lactose-free options use alternatives.
- Vitamins & Minerals: Including iron, calcium, iodine, phosphorus, sodium, folic acid, vitamin D, vitamin C, and vitamin E.
- Fatty Acids: DHA supports brain development.
- Other Ingredients: Taurine and specific amino acids may be added to support overall growth.
Skim Milk, Whole Milk, and Why It Matters
Formulas may use skim milk solids combined with added fats to reach the right energy balance. Baby Steps uses only whole milk, which is naturally rich in good fats that support growth, brain development, and gentle digestion. Baby Steps Infant Formula is made with premium New Zealand whole milk that supports growth and brain development. This ensures babies receive adequate fats for healthy growth while keeping protein levels appropriate for young infants.
Matching Formula to Your Baby’s Age
Formulas are staged by age to align with changing nutritional requirements:
- From birth: Designed for newborns.
- From 6 months: Supports babies starting complementary foods while continuing formula feeds.
Always choose a formula appropriate for your baby’s stage and maintain consistency unless advised otherwise.
Preparing Formula Safely: Step-by-Step
Safe preparation protects your baby and preserves nutrients:
- Wash hands and sterilise the bottle, teat, and utensils.
- Boil fresh water and allow it to cool to the recommended temperature.
- Measure water first, then add the correct scoops of powder.
- Secure the lid and shake gently until dissolved.
- Check temperature on your wrist before you feed.
Improper handling or storage of feeding equipment can increase the risk of infection or illness in young infants.
Avoid reheating with excessive heat and never add extra scoops of powder or water.
Supporting Digestion and Comfort
Some babies experience wind or an unsettled stomach as they adjust bottle feeding. Helpful tips include:
- Holding the bottle so the teat stays full to reduce air intake.
- Burping during and after feeds.
- Choosing formulas with adjusted proteins or without palm oil if advised.
Persistent issues should be discussed with a healthcare professional.
Nutrients That Matter for Healthy Growth
- Iron: Supports oxygen transport and development.
- Calcium & Phosphorus: Build strong bones and teeth.
- Iodine: Important for growth and metabolism.
- Vitamins D, C, E: Support bones, antioxidant protection, and overall health.
- Amino Acids & Taurine: Assist metabolic processes.
- DHA: Contributes to brain development.
Together, these nutrients help babies thrive during rapid early growth.
Formula Feeding at Home and On the Go
Being organised makes feeding easier:
- Keep pre-measured powder in a clean container.
- Carry sterilised bottles and access to safe water.
- Store opened tins in a cool, dry place and use within the recommended time.
Avoid using formula past its use-by date and keep lids clean to prevent contamination.
Balancing Breastfeeding and Formula
Many families combine breastfeeding with formula. This flexible approach can support supply, shared feeding, and parental wellbeing. Transition gradually and watch your baby’s cues.
