Thanks Portia. Does your child ever turn to anyone else to help him work through his anxiety? Is it always you? have you ever had any success in broadening out his support network?

And one more question if I may - how do you test for GABA levels? We've collected over the last few months lots of homeopathic remedies, sleep sprays and some herbal supplements, but I've not done any form of medical testing. Something to think about maybe....
