Thanks ladies.

Starfish - I'm not worried as such (provided its not anything that's going to lead to her stopping feeding). She's not hideously distressed or anything - just crying and grumpy. I have no concerns that she isn't getting enough milk because she's a beautiful little buddha growing out of her clothes seemingly daily. The biggest problem is the damage she's doing to me and that feed times can be unpleasant for both of us, and my other girls if they're around.

MadB - plenty of really wet nappies. I'm going through about 8 cloth or 6 disposables a day (ie between 7am and 9pm)

TC - thanks. Hadn't thought of that.

RCC - will give the ABA a call and see what they think. I'm so determined to keep feeding that I think I'm avoiding calling the ABA because I don't want anyone "official" telling me there is a problem. Nothing like putting your head in the sand!
