CL, if you go to the dietician association website - Dietitians Association of Australia (DAA) : Find an APD - and select allergy/food sensitivity in the area of practice, you might find a dietician near you who specialises in this. I know of one really good one in WA but she is probably in Perth.

black_rose, did you read the article I linked to? It might be helpful for you to know that your DD's problems were not caused by lactose intolerance. If she had been lactose intolerant she would not have survived for 8 months - I mean literally would not have grown at all and would have needed severe medical intervention to stay alive. This is very, very rare. Most likely your DD had either reflux or food allergy/intolerance (not lactose though!). Do you know of any food sensitivities that she has now?
