Preparing a bottle

4 easy steps to a ready bottle.

Each sachet is labelled with the exact amount of water to add, so there's no guesswork.

Before you start: clean hands, clean tools.

Wash your hands with soap and water, and make sure all bottles, spoons and containers are sterilised before use.

  1. 1

    Add water

    Start with room temperature or slightly warm pre-boiled or purified water (about 38-40°C).

    Always measure the water before adding powder, using the amount on your label.

    ★Water first, then powder

  2. 2

    Add the powder

    Gently squeeze the sachet or use the provided frother to loosen the compacted powder fully, then pour it slowly bit by bit into the bottle.

    ★Loosen powder first

  3. 3

    Swirl and mix

    Swirl well until it dissolves fully. If needed, stir gently with a sterilised spoon.

    Higher-fat milk can take a few minutes to mix.

    ★A creamy look is normal

  4. 4

    Test the temperature

    Drip a few drops on your wrist. If it's too hot for you, it's too hot for bub.

    ★Then it's ready to feed

Warming and mixing tips

✕ Don't Don't microwave

Skip the microwave when warming your milk, even for a few seconds.

✓ Do Use a bottle warmer

If you refrigerated your reconstituted milk.

Good to know Creamy is normal

Milk with more fat can look creamy and take a little longer to dissolve. Give it a few minutes.

Adding into solids

Mix it into bub's food!

Not every feed has to be a bottle. Sprinkle the powder straight into solids for a little boost of mama's best nutrition.

Mix it in wellStir thoroughly so there are no dry clumps, and to avoid bub accidentally breathing in loose powder.

Cereal, oatmeal and mashed fruit

Stir it into bub's cereal, oatmeal or mashed fruit.

Milkshakes and yoghurt-style blends

Blend it into smooth, creamy mixes.

Dipping sauce for finger foods

Mix up a dip for soft finger foods.

Questions

Feeding questions, answered.

Each sachet is labelled with the exact amount of water to add so there's no guesswork. 

As a guide, a ~15g sachet makes about 125ml. Always measure the water first, then add the powder.

Milk with more fat can look creamy and take a few minutes to dissolve fully. The key is to loosen the powder fully and add them in slowly while stirring. 

Stick to room temperature or slightly warm pre-boiled or purified water, around 38-40°C. Hotter water can cause more clumping.

No. Condensation in the fridge can spoil the powder. Keep opened sachets in a cool, dry indoor place and use them within 2 to 3 days.
