<<Disclaimer: Verify this information before applying it to your situation.>> My 7 year old 'gluten intolerant' son started chewing his fingers and nails about two months ago. I started using a product called Stop'n'Grow. He was unwell almost immediately. At first I didn't think of it, but after 3 days, it dawned on me, duuuhh! It probably had gluten in it. We stopped using it, and after 4 days he was getting better. I called the company who reassured me that there was nothing derived from gluten in it. So we used it again, and yes, almost immediately he is unwell again, belly ache, diahorrea, cranky, tired. Has anyone else (we are in Australia) encountered this? Do you have any other solutions for helping him to stop biting his fingers? We have tried to get to the bottom of it, no problems at home or at school, in fact after finally getting this celiac under control, I thought everything was finally okay. Out of my 5 kids, he is the one who has had every problem going and I am surprised he didn't start nail biting years ago. Delayed reaction now he is better maybe? I will stop waffling. Any thoughts are appreciated. Thanks Tracy Tracy Fleming [log in to unmask] Australia
