Ok so I pump during work and put my milk in a little cooler to stay cold. Well I came home today and forgot to put it in the frig before we went out to dinner. I came home to make his bottles/sippys for tomorrow and the cooler pack wasn't cold at all. It was room temp. The milk was kinda right about room temp but not cold. I smelled it and it smelled fine. Do you think it would still be already for tomorrow. If the milk smells ok does that mean its good?
