I'm so sorry that you're not getting results. Its heart wrenching for her and you - especially when you don't know that it even is helping. Especially on so few foods
I really would be considering formula after a set amount of time has passed. Kai really was better by 6-8 weeks on the diet, I was eating low to moderate chemical with no allergin foods.
I should probably tell you about the supplements that I have Kai on - prescribed by my naturopath. She is quite knowledgeable in failsafe, food intolerances and allergy. She says that the sensitive babies often don't have enough enzymes required to metabolise the food chemicals, they get more as they mature, the chemicals tend to build up adn they need extra help with the load on their kidneys and liver. So we give the following to assist him:
1 teaspoon glycine -immune system
3 tabs transfer factor - immune system
2 drops zinc - clearing out toxins
1/2 cap activated B6 - clearing out toxins
1/2 teaspoon probiotic
He has been on these for about 4 months and I really think its the key to him tolerating a higher amount of sals, he is now on tablespoons of high per day + unrestricted moderate. He is also tolerating some buffalo yoghurt and goat milk.
