Sherie, I'm pretty sure it's reflux as I've seen it before - she starts off feeding ok, then it starts - she's still hungry and wants to feed but arches her back and cries (with her mouth full of boob) and then the chucking starts (but it hurts and she doesn't settle afterwards like they do when they've let out a good windy burp or even a posset -if anything it hurts more). She was a happy chucker up until a few days ago and I've not eaten anything different in that time...but I'm on to it early and I'm pretty sure the treatment will go into effect before it turns into a nasty chronic painful thing. It's just a pain cos all the medecines are a bit of a pain to administer - I remember trying to mix up ridiculously small amounts of gaviscon powder for DD1. But Zantac and Losec have come along since then so we'll see what the Dr says tmrw.
