Making up bottles

Make sure your bottles and teats are sterilised and that you’ve washed your hands thoroughly before making up the bottle. If you're using infant formula, follow the instructions on the packaging carefully when you make up the feed.

Step-by-step guide to preparing a formula feed

Step 1: Fill the kettle with at least 1 litre of fresh tap water (do not use water that has been boiled before).

Step 2: Boil the water. Then leave the water to cool for no more than 30 minutes, so that it remains at a temperature of at least 70C.

Step 3: Clean and disinfect the surface you are going to use.

Step 4: It's important that you wash your hands.

Step 5: If you’re using a cold-water steriliser, shake off any excess solution from the bottle and the teat, or rinse them with cooled boiled water from the kettle (not tap water).

Step 6: Stand the bottle on the cleaned, disinfected surface.

Step 7: Follow the manufacturer's instructions and pour the amount of water you need into the bottle. Double check that the water level is correct. Always put the water in the bottle first, while it’s still hot, before adding the powdered formula.

Step 8: Loosely fill the scoop with formula powder, according to the manufacturer's instructions, then level it using either the flat edge of a clean, dry knife or the leveller provided. Different tins of formula come with different scoops. Make sure you only use the scoop that comes with the formula

Step 9: Holding the edge of the teat, put it into the retaining ring, check it is secure, then screw the ring onto the bottle.

Step 10: Cover the teat with the cap and shake the bottle until the powder is dissolved.

Step 11: It's important to cool the formula so it's not too hot to drink. Do this by holding the bottle (with the lid on) under cold running water.

Step 12: Test the temperature of the formula on the inside of your wrist before giving it to your baby. It should be body temperature, which means it should feel warm or cool, but not hot.

Step 13: If there’s any made-up formula left in the bottle after a feed, throw it away.
