I used a Boppy pillow for our first LO, and was not a big fan. I'm small chested and felt like it didn't give me any support so I ended up using a few pillows instead.
I'm looking at buying a Brest Friend pillow, but someone suggested a nursing arm pillow, similar to this one:

Anyone use either one and loved or hated it?
