A baby’s immune system is not yet fully developed, and babies are more susceptible to infection and illness than an older child or adult. Cleanliness is therefore very important when preparing your baby’s bottles.
Bottles, lids, teats and other equipment you use to prepare a feed should always be thoroughly cleaned after each use:
As soon as possible after your baby finishes a feed, wash the bottle, teat and lid in hot soapy water.
Use a bottle brush, and be sure to clean out any dried milk stuck inside the bottle and teat.
Once it is clean, rinse the equipment with some fresh water and allow it to dry.
This kind of cleaning is important for getting rid of all traces of milk or formula left inside the bottles, but it does not ensure that the feeding equipment is completely germ-free.
Sterilising is the process of killing any harmful germs that may be clinging to surfaces of the bottles and other equipment.
It is important to sterilise baby bottles before each use, for at least the first 12 months of your baby’s life. This applies whether you are bottle feeding with infant formula or with expressed breast milk.
