Hi L.,
With Candida, if you want to go with an all natural totally safe non-toxic product that works, it's Threelac, I heard that they just came out with an even better product called Fivelac. Candida starts in the gut so the creams will give temporary relief but you have to address it from where it starts. These products are delicious tasting lemon flavored powder that you can put in your son's food or even in a bottle, it is lactobacilus that eats Candida, that is all it does. The results are quick and safe. The company that sells it is in California called GHT and the number is 800-305-5710. It is a bit expensive but you can buy whole sale and they are a great company who will give you a full refund within 30 days for any reason. And any amount is worth it for your little guy. I am sorry for his discomfort, I know that itching!!! I promise you this stuff works so well and fast. You can google it also to find more about it, it's all over the internet as I think it's an MLM but you don't have to bother with that. Please trust my long, very long time experience, you don't want to start your son on nystatin and things like that. Best to you and your son. Warmly, C.
