My son is 2 and spent approx 18 mths headbanging. I can’t say for sure, but it could possibly have been approx the time we removed 160b from his diet that he stopped. I removed 160b along with the other additives you recommend avoiding to help manage my son’s behaviour. It has seemed to work very well. Adjusting his diet has made being a parent so much more enjoyable and I would like to thank you for this.

We removed the 160b (and all the other additives) approx 5 -6 months ago. We had a major relapse at Easter. This confirmed my suspicions and made my husband realise that the food additives did affect our child.

On looking back, our son stopped headbanging around this time, but I can’t say whether it was as a result of the changed diet or not. I didn't realise until seeing your talk a few weeks ago, the headbanging could be related to 160b. The foods my son ate that contained 160b were cheese slices, margarine and yoghurt. I’m sure there would have been others, but these are the ones he ate every (or almost every) day. – Heather, by email
