How to clean and store baby milk bottles?

Hi everyone, I'm going to be a first time mum soon and questions on cleaning baby's bottles come to mind. Hope to get some advice and tips!! - After washing the baby bottles, where do you store them? - After using a UV steriliser to sterilise bottles, where do you store them? How long do they stay sterilised? - Do we have to sterilise bottles just before adding in the milk for baby? Or ok to use bottles that have been sterilised 2-3 days before? - Any special storage I need to get to store bottles? Any other tips would be helpful. Thanks so much!! #firsttimemom
