I will be traveling out of town for 3 days without my 3 month old. Any travel tips from people that have been there? How is it going through airport security with milk? What did you store pumped milk in? Will my milk be ok in a hotel mini fridge then in a a cooler during travel to and from? I have low supply, so I really want to make this work while I'm away; the thought of pumping and dumping makes me want to cry!
