Just wondering...I'm FT FF and I sterilise the bottles every morning in a microwave steriliser, I then pour in cooled boiled water into the bottles and seal them (with teat & cap) and let them sit on the kitchen bench until required. I then add formula, shake and use (no heating or anything).

Is this ok??? I mean, is the water ok to be left at room temperature inside sealed sterilised bottles? Or should I really be keeping the bottles with water in them in the fridge?

Thanks
