I'd keep an eye out for white patches in the twins' mouths. Or a diaper rash that has little red bumps. If you see either of those, you've given the babies thrush.
There are lots of things you can do to treat it. Dr. Sears Thrush Info
A little pet peeve I have is people starting threads in bfing with cryptic subject headers. It might help if they would put something abt the problem in the header. Like , instead of "help!," you might put, "shooting pain in breast." Maybe you would get more response from women who have BTDT.
Glad the pain went away. It could've been a touch of thrush that just righted itself. You may want to take acidophilus daily anyway, just in case it isn't really gone.
