Our daughter is lactose, soya and egg intolerant. At birth and for the first few years she was strongly intolerant now aged 5 she has some limited tolerance. Has had skin prick tests etc and is not allergic, just intoletant. She was on Neocate formula when younger, now has a combination of lactose free milk and normal milk with colief lactase drops. She can tolerate limited amounts of normal cheese (eg a couple of slices of pizza) but also has the lactose free products. The soya intolerance limits the dairy replacements, for example she can only tolerate two soya yogurts per week, which is a shame as she prefers those to the lactose free ones. We just have to manage the amount of dairy, soya and egg she consumes, normally avoid products with these as a primary ingredient but OK with smaller amounts. Although her tolerance has increased in the past couple of years I expect her intake will have to be managed to some extent for life.
