I have to go away for work. It is just over night but I am still worried about it. I just don't want to leave my baby... Anyway I have to and I am going. I leave on a TH am and fly back home on a Fri pm. I am going to have to pump a ton because mom son usually nurses around the clock besides when I am at work. I am planning on calling the airlines to see if I have to check the milk to bring it back or if I can carry it on. I know I have to have a cooler but I am curious what I should do besides that? Use dry ice, just a lot of normal ice in the cooler with the milk? I do not think that I have a fridge in my hotel room and I know that I will not have access to a freezer. If I do need dry ice do I buy it at home and fly it there? I don't have a car where I am going so going around trying to find dry ice will not be possible.
