Due to issues breast feeding I’m switching over my little one to formula. I am starting with night feeds and DH has got us a perfect prep machine. We are cold water sterilising so getting a bottle out when we need one. Overnight my LO likes to be held so I struggle to measure out the formula without putting him down and him screaming while I make it. I was wondering I could have a sterilised bottle with teat etc built with the powder next to the machine ready to prepare when the time comes or will that not be sterile?
