dd will be 1 years old soon, so we are doing the formula to cows milk transition, just wanted to know what do you do when you go out? Surely you cant bring a bottle of fresh milk in a milk bottle for several hours without refridgeration? or can i? Or just buy milk when you go out? It was so easy when i was on formula, just to bring cooled boiled water out and mix up the milk and powder when she ready to drink, but i dont know what to do about fresh milk....any advice?
