My pump (the Ameda lactaline personal, it's called something slightly different in America) has been in fairly continuos use, three times a week day for about 2 months now. I think that it has become less efficient (or my supply has taken a drop, but I don't think it's that).
I remember reading posts which said that you can expect to change certain pump parts every 2-3 months. I couldn't find the post and I'm not sure what to try. Can anyone advise please?
