There is a website called Pollywog, it is a shop however they have easy to read info on reflux bubs, which I have found helpful.

My baby hasn't lost weight so the GP won't give us meds, but apparently meds are pretty ineffective. The only product that sometimes helps him is a Baby Probiotic, and I have just found out Inner Health Kids is cheaper than the one I was buying. It sometimes cuts back on his chucks but on the whole he is just more comfortable with the probiotic more than anything else.
