My son is 7 now, since he was about 6 we started noticing him doing unusual actions with his body. After some research we realised its Tics. We also found out that there has been this type of tics in my husbands family. Its not very bad - more impulsive body movements. I have researched that caffine products and diet high in salicylates can make tics worse. I would be grateful if anyone can advise me on what foods are best and any other useful help. Many thanks.
