Hi,

There is a significant correlation between cows milk protein allergy and reflux. There's a great book written by Brian Vartabedian (paed) who will be speaking in Australia next year called "colic solved" but also deals with reflux etc. It is available from Mothers Direct
Are there any other family members who have allergies/food intolerances? This can often offer a clue. Is there a history of eczema or asthma in the family?
