I ordered a larger flange for my breast pump because during the pull, part of my nipples were rubbing against the tubes and it was a little painful. I got the new flanges today and tried to use them but barely got any milk suppressed. I can't figure out if it was because I just didn't have enough or if it the new ones are just too big.
Re: If the flange is too big on your pump, will this slow down the expression?
