My boy is 4 months old GP has prescribed Neocate as advised by health visitor and infant feeding team he's been on Aptamil Pepti 1 for over 3 weeks with no signs of improvement to his skin. Gp has scheduled us back in for app on Tuesday he said this will be passed onto specialist. He also said something along the line of Atopic exzema auto immune response could be possible other allergies. Who are the specialists and what could this mean?
