HI there I don't know of any allergists in Melb, but I have one here in Perth too and if your bub has had skin Pr*ck testing it really is the better test than the RAST blood test on a little one. Basically for them to get a reaction to either the skin pr*ck or the RAST they have to have quite a bit in their system generally, that is why these ways are unreliable in the first 4 or 5 years.

The other thing that it could be is intolerences, we too went to advanced allergy elimination and it did do something for Parkers intolerences, but didn't cure them like they said they would, he used to react to everything and I could never pinpoint them, and once we finished AAE the rashes on his face etc... seemed to clear up.

If you are dealing with intolerences, it is hard because reactions may take up to 3 days to show, which makes it really hard to pinpoint them, Sue Dengate, does fed up with food additives and has a special diet for kids with intolerences that is really well received.

Good luck finding an allergist, it is definately worth talking to someone who is knowledgeable on the subject and will point you in the right direction.
