I know that toddlers can be a bit fussy in their eating habits and decide to restrict their food intake but DD eats very few foods apart from fruit. She eats almost no protein at all. She often just pushes her finger into food then refuses it. Recently she has started retching to the point of being sick just touching or looking at cheese. Does this sound familiar? I don't know of any other toddlers whose diet is so restricted and wonder whether I should be worried, especially about the retching/vomiting bit...
