Hello I bought philips avent feeding bottle. what Is the first procedure to use. how to use? can anyone explain?

A. Hello mam it is very important to sterilise the bottle when you buy a new bottle. So what you can do is that you can boil the water into the boiling water after washing it properly or else you can wash The bottle really properly and after that you can keep it in the deep freezer for at least 2 to 3 hours as that also sterilises the bottle properly and once you do either of the two things then you are bottles are ready to be used to feed your baby
