I am completely new to this board. My 12 year old son is the one with IBS. I have ordered the diet kit #2. can I use an adult dose with him? I'm hoping for a miracle. Some days are ok, but some are so awful that I just want to cry for him. He asks me all the time if there is such a thing as a stomach transplant. If there is any advice you can give me, I would greatly appreciate it.
