I'm trying to figure out which one to bring with me on our trip that works well on the airplane.
I just saw that there's a travel inflatable version of the Brest Friend, but we fly out Saturday and I can only get it online.
Instead of a big pillow, I found that an inflatable 'camp' pillow works great! It folds down to almost nothing in your bag, and then you can just inflate it to the degree that you need, and then rest your elbow/arm on it on the side you are nursing on. It worked great for me when we went to Scotland with my older daughter who was 5 months. I could also use it in restaurants too.
