Hi,
I was planning on giving my baby room temp bottles... so on a morning I would boil a kettle full of water and then fill the bottle up with it throughout the day and add the powdered milk as and when the baby wants it. This is what my mum did with my and a few of my friends seem to do as it seems the easiest way.
Midwife said to me this used to be the way but it has now changed as they've worked out the powdered milk is not sterile so needs to have a boiling shot of water added to the milk before use. What does everyone else do?
