If the problem is excema, you could try Dr Loubser at the Infinity Clinic - he is a Paediatrician with specialist expertise in childhood allergies. We are seeing him for my DD's excema currently.
Dr. Nasir is excellent, I agree but I just called his office a few days ago and he is still away on medical leave. They took my number and said they would call when he returns.
Oh dear - poor man it's been quite a while now I hope he's making a good recovery. If you call Dermacare they are really helpful in there they might be able to recommend someone in Dr Nasir's absence.
