What Is Infant Formula?

Infant formula is a specially made powdered milk alternative, usually based on cow’s milk with added vitamins, minerals, and fats from vegetable oils. It’s designed to support your baby’s nutritional needs from birth to 12 months. Formula can be powdered or ready-to-drink and is typically offered in a bottle.

Some formulas are made with soy or rice protein for babies who can’t tolerate cow’s-milk protein. These specialty formulas should be used only under medical advice.

How Is Formula Different?

Formula differs from cow’s milk and breast milk in several ways:

• Babies under 12 months should not have cow’s milk as their main drink.
• Breast milk contains antibodies and changes composition to meet the baby’s needs.
• Formula offers a consistent nutritional profile but lacks natural antibodies.
• Formula generally contains more protein than breast milk.

Reasons for Choosing Formula

You may choose or need to use formula if you:

• Have trouble producing enough milk.
• Are taking medication or have health concerns that prevent breastfeeding.
• Are separated from your baby due to work or caregiving arrangements.
• Are an adoptive parent, foster carer, or in another caregiving role.
• Have experienced trauma or choose not to breastfeed.

Mixed feeding — combining formula and breast milk — is also an option.

Types of Infant Formula

• Milk-based formula: The most common, made from cow’s milk.
• Soy-based formula: For babies who can’t tolerate cow’s milk.
• Specialty formula: Modified for babies with allergies or digestive issues.
• Enhanced formulas: Contain additional ingredients to mimic breast milk.

Always consult a healthcare professional before using specialty formulas.

Tips for Choosing Formula

• Choose a formula based on your baby’s age and health.
• Cow’s-milk-based formula is recommended unless otherwise advised.
• Price doesn’t always reflect quality — choose what’s affordable.
• Monitor your baby’s reaction before changing brands.
• Avoid formulas with high protein content, which may affect weight later.

Formula Allergies and Intolerance

Babies sensitive to cow’s-milk protein may show signs of discomfort, rash, or digestive problems. In such cases, a hydrolysed formula with broken-down protein may be recommended by your healthcare provider.

Recognizing Hunger Cues

Signs your baby is hungry:

• Crying
• Sucking on fingers
• Clenched hands
• Focused and alert posture

Signs they’re full:

• Slower sucking
• Turning away
• Spitting out milk
• Relaxed body

How to Prepare Infant Formula

Before you start:

• Wash and dry your hands.
• Use sterilised bottles.
• Read container instructions carefully.

Steps:

1. Boil water and cool to room temperature.
2. Pour the correct amount into the bottle.
3. Add the recommended scoops of powder.
4. Shake the bottle until the powder dissolves.
5. Test the temperature before feeding.

Preparation and Hygiene Tips

• Use clean, sterilised bottles and teats.
• Prepare each feed fresh.
• Store unused formula in the fridge (coldest part).
• Discard any leftover formula after 1 hour.
• Avoid microwaves—warm bottles in hot water instead.
• Travel with formula powder and pre-boiled water separately.
