Non-dairy yogurt

My son, Cael, has a sensitivity to dairy products.  It can be challenging finding non-dairy versions of food that are somewhat healthy and not loaded with sugar or that seem to have no nutritional content.  I've been considering trying my hand at making some yogurt for him, but it's kind of a nerve racking food to attempt- so many things can go wrong.  I spent a couple weeks researching recipes from other people, and non of them seemed perfect, but also so may variances in the amounts of certain ingredients that would make the yogurt set up.  I sort of went off 2 different recipes, but also modified them and developed my own recipe.  I made a coconut milk yogurt, as it seemed like it might be nice and creamy.  So far it seems to be setting up great, but I'll know in the morning after it's had time in the refrigerator.  My experiement didn't seem to go too bad for my first attempt.
