Staying in a hotel when I go on my first night out and my partner will be feeding our baby formula for the first time. We will use the pre made formula but how on earth do you steralise a bottle in a hotel room? I have exclusively breastfed up to now so have no idea how to steralise a bottle.. am clueless and terrified of getting it wrong and making little one ill! it is a one off so don't want to buy anything we can avoid. We won't have access to a microwave. How do you do it?!
