I'm going out for several hours for the first time tomorrow since having my baby a couple of weeks ago. Please excuse my stupid question and hold my hand as I'm so nervous! I am going to take my thermos of boiled water and a pot of formula feed but I want to know how to quickly cool down my thermos of hot water ( as my baby goes from 0 to screaming for milk in minutes). Also do you have a special bag or container for the bottle? I don't have this, was just going to put in my changing bag.
