Yeah, so we make and prep bottles instead of doing one batch. We usually only prep so many bottles as should only be kept in fridge for 24 hrs. And we reheat using bottle warmer. Is very useful during night (still waking up 2x) but also when I was very ill and was struggling looking after little one when husband was working.
I just used to make up all my bottled as normal and fridge them for 24 hours, as long as baby hasn't had the teat in their mouth it's fine :) x
