If you are bottle feeding your baby, whether entirely or supplementing your breast milk, you need to know how to prepare formula milk for bottle feeding, and how to store milk correctly. If you follow a simple set of rules, it will be quite easy.

If you are using powder, always follow the receipe on the formula packaging, this is important for the child to receive the appropriate nutrition. If you add too much water it dilutes essential nutrients in the formula and your baby may not get all the nutrients that is needed to grow and develop. If you add too much powder, you risk damaging the child’s kidneys.

How to prepare formula for bottle feeding:

  • Wash hands before you start
  • Clean table and surroundings before you prepare the bottles
  • Make sure bottles and teats are clean and sterilized before preparing the formula
  • Use fresh drinking water to prepare. If using tap water always use cold water and let it run a little before putting into the kettle
  • Boil the water
  • Let the water cool for about 30 minutes (minimum temperature 70 degrees) before mixing with formula
  • Mix powder (follow the producer’s receipe to get the right amount!) and water, and shake the bottle well for the powder to dissolve.
  • Cool the bottle in cold water/ice water and check the temperature before serving.
  • If you are making more bottles at the same time, it is very important to cool them immediately in ice cold water and store them in the fridge. (5 C or below)

It is ok to store baby bottles with mixed baby formula in the fridge for up to 24 hours, you may then heat them when you need them. This means you e.g. can make all bottles needed for nightly feeds before you go to bed, keep them refridgerated and heat baby bottle in seconds in the microwave. Of course using milkymeter to make sure you get the right temperature. If you are heating them in a hot water bath, do not leave the bottle in the warm water for more than 15 minutes as you then risk for bacteria to develop.

Making bottles in advance will save you precious minutes (especially at night) and save baby from becoming too hungry and upset. However, cannot be recommended if your baby is prematurely born or younger than 2 months old.

Never save a half bottle of milk which the baby has already been drinking from. Bacteria may develop which can be harmful for your baby.

Oh, and by the way, it is ok to switch between different forms of the same formula type so you for example can use powder for everyday use and ready made when travelling.
