personally I would go straight to a peadiatrician as my bub had severe reflux and my gp put him on the reflux formula and over time he got a really bad rash which my gp just said was eczema as it was under his chin and down the front of him. I got an appointment with my peadiatrician and the moment he looked at him he said he had a dairy allergy. We put him on Prescribed formula and over a month his reflux had nearlly dissapeared and he was such a happy new baby.
