Sure I don't think it was my mother's fault, she wanted just the best for me. And talking of this, what do you think I should do with my 2 yo child? He's very smart and energetic, and doesn't have any of the symptoms of HIS, but I want to think of some form of preventive supplementation. Before, I'll test it together with Erik. Maybe I'll paint the sole of his feet every now and then, or put a drop in the oatmeal (it would come out quite a nice color!)
