Preparing for overseas trip

I find the portable Uv Steriliser bulky so I always use the steriliser bag. there are a few brands but I buy the Medela one. Just need to place bottle in the bag. Typically can fit 2 large size Avent bottles. Pour some tap water at a certain amt and microwave it. If no microwave, use sterliser tablet. You wld need to soak it for a certain time first before putting in bottles. This takes longer than the microwave bag method. And I don't really like the smell of sterile water as there's a lil chlorine smell.
