Hello, I'm wondering if any experts could help, please? We are going away on holiday to Australia in two weeks and my LO will be 2 months and I'm still breastfeeding despite having severe anxiety with it. Of course, I want to breastfeed as much as possible but for those times I can't, I will be bringing expressed milk. My question is, will milk that has been expressed be suitable to be stored in the baby bag in really hot climates or will I need to take precautionary measures (cool bag) to keep the milk safe. I'm sorry if this seems like a silly question, I just can not find anything about the storage of expressed milk in higher temperatures anywhere online. If anyone can please could you send me the link. Kind regards
