Perhaps you and your child might start by making an SCD recipe, a meal or a dessert that appeals to your child. This may get her to buy in before actually starting the diet. I recommend you begin with the Monster Cookie recipe in Elaine’s book, Breaking the Vicious Cycle. I tried this recipe before committing to the diet, and the cookies were so delicious I was encouraged to finally adopt the SCD. That was 5 years ago. All my friends and family love those cookies. If you decide to do the SCD you will have to learn to cook and bake food that you can share and enjoy anyway, so I think it would be a good idea to try a few recipes, just to see if you could imagine preparing and enjoying SCD meals and treats. Considering that your daughter is well 95% of the time, you may have the luxury of introducing the diet slowly, recipe by recipe until your child is happily compliant.
