I thought I'd try the Gerber nursing pads; they're admittedly cheaper than the other brand I'd been using. Horrifyingly, when I went to pump at my first break (less than an hour after putting the pads in place), my nipples were stuck to the pads. I cried peeling them off.

I thought maybe I'd placed the pads when my nipples were damp from nursing my son, so I waited several days for the nipples to heal, placed them when they were dry... again, same problem with the sticking. I won't ever use them again.
