I think Inez is allergy to egg yolk... This morning I cooked white rice porridge with sweet potato, cauliflower and egg yolk as her lunch and at around 7pm, I noticed little rash beside her mouth and under her lip.. Is this the 'oral rash'? It look quite itch and a little swollen to me but Inez never scratch her mouth leh... What shld I do now? Bring her c pd or??
