robinw - why would you believe an nz allergist site over baby milk action? Wouldn't you be better going to somewhere like pubmed looking at all the evidence yourself and making a decision?
With reflux, as far as I understand from DD's misdiagnosis of having it last year, the problem should sort itself out within a few days of taking the medication, if it is reflux. If it isn't (as per DD), it won't. Taking 5ml of mediciine twice a day for a week is prob less traumatic than 24 hours of ph monitoring which involves sticking a probe down the child's oesophagus and I suspect most paediatricians wouldn't even contemplate that.
