My 7.5 month old DD has a cows milk allergy (she's on Nutramigen milk) and probable egg allergy (as per skin prick test) and quite bad eczema. The skin prick tests she had done a few weeks ago gave a positive result to wheat & soya too, but not quite so strong a reaction as to milk and eggs. The doctor (a dermatologist) said I should not exclude wheat & soya from her diet, as "you can't exclude everything". But I'm quite nervous about trying them. At what age do you think I should first try? And what about tomatoes? Thanks
