Babies are prone to bacterial infections, as the immune system is still weak. Pathogens can be transmitted in the baby food, so for this reason teats and bottles should be sterilised thoroughly. Why this is and how it works... Sterilising by Boiling Chemical Sterilising Steam Sterilising

Preparation

All parts that need sterilising must first be thoroughly cleaned. This is very important, as only clean parts can be sterilised properly. Simply washing the parts is not enough, as even the tiniest food particles can turn into breeding grounds for harmful bacteria.

The best procedure is as follows:

	Thoroughly clean all parts after mealtime.
	Clean the teats both inside and out, and rub thoroughly.
	Rinse thoroughly once more. We recommend that you also force water through the feed hole to ensure that this is also free of any food particles.
	All breast pump accessories such as bottle, suction funnel, seal, screw ring and lid should be thoroughly cleaned and rinsed with water after each use. This is important so that no milk remains are left. Milk easily forms a residue that can turn into a breeding ground for bacteria. The accessories should be sterilised at least once a day, preferably in the morning.
	Once all parts have been cleaned thoroughly they can be sterilised, for example in the Steam Steriliser.
