I am 42 and live in Sydney with my husband and 2 children. My story centres around my son, Alex who is now 6 years old. Alex is a little toughy, one of those kids who is highspeed, enthusiastic, in your face, adventuresome etc (and that's with a positive spin on his life).

He was born 2 weeks early, but a big boofy boy at 4kg. For the first 6 months he was a wonderfully placid calm child. Feed well, slept well, grew well, didn't seem to cry - dream baby. (Apart from having chicken pox, bronchiolitis and 2 fits in this period he was healthy and strong - though perhaps these illness should have given me a clue).

At six months he suddenly became incredibly restless - people would comment on him being active and a real 'tiger' - Looking back 3 things changed at this time - he started solids, started formula and he started daycare. I also remember noticing his face change. He had had a beautiful round baby face with bright blue eyes, and when he started on solids he got dark circles and creases under the eyes, and his eyes turned green - I remember crying at the loss of my beautiful baby boy.

His first year in day care was diabolical. In a class of 15 babies, with 4 carers they could not cope with Alex. He walked at 9 months and spent his time running around the other babies (that were still immobile) snatching toys, jumping on the babies, shrieking, and escaping - he seemed incredibly bright and had the mobility of a child at least 6 months older. Every evening I was met with the litany of what he had done that day to terrorise the class. The carers always looked frazzled and worn out. Their only solution was to give continuous time out as a unishment - he spent hours every day in a cot that he eventually broke - at the time I lived through it thinking it must get better - in hindsight I see their approach as completely inappropriate - he was too young to be punished - it didn't help to modify his behavior, rather it set it in stone.

He continued through daycare being rough and ready, and some days violent - he found their order and routine hard to take. When he wanted to run in the garden, he had to listen to the story, when he wanted to keep painting, he was told painting time was finished - the structure and lack of freedom drove him mad. And this was a university based childcare with great facilities and high staff to student numbers!!

Our life at home was crazy as well. It was like living with Jekyll and Hyde. Sometimes he would be a delight, other days he would be totally uncontrollable - usually incredibly defiant - he could stick to his point hour in hour out - it was impossible to win an argument - normal parenting didn't seem to work. He also had a habit of making loud repetitive noises.

Going out was a nightmare - he would run away, run into traffic, swear at strangers, try to strangle other children, and on a really bad day would threaten to kill people. There were many times when I felt that I had a potential psychopath or serial killer on my hands. Another characteristic was that he couldn't be told anything - he always wanted to learn first hand.

Harm minimisation seemed to be the best policy - I taught him to cook, use knives safely, chop wood with an axe, use power tools etc at a very young age - on the basis that he was going to find and use these items anyway, no matter what I did to try and stop him. Although he had a few accidents (mainly burns from cooking) this strategy has meant that he is still alive.

At 3 we discovered he had asthma, and glue ear - he had his first set of grommets inserted and could finally hear. At that stage I thought the hearing was the answer to all his behavioral problems, and I am sure he must have felt better being able to hear (Since then we have had another 3 sets of grommets inserted). He also changed to a community based, child centred pre-school/school which was far better for him. They worked with what he wanted to do and let him learn and explore at his own pace. The other children were attracted to him in an odd way - they were always excited to see what daring deed or brilliant idea he had - he never lacked for incredible ideas or enthusiasm. Despite this, successful social interaction and aggression was still an issue, and friendships were dicey due to his unpredictability.

Another habit he had was ticcing - eye tics, snorting, touching other children, kicking - At 4 he was diagnosed with Tourettes by a paediatrican. (I followed up later with a neurologist who specialised in Tourettes who said that he was just a naughty boy who needed counselling).

I was also seeing the local health centre psychologist -but this seemed to be no more than a chance for me to talk - never really got to address Alex's needs.

Interestingly I found his behavior was always better in winter, and was diabolical by term 4 (I now think this is fruit related!).

By the end of pre-school several parents had started a petition to get him removed from the school - luckily I had the support of the teachers and many other parents and this was stopped dead in its tracks.

I noticed that there were several different levels to his behavior - what I think of as 'full on' and then 'psycho'. I noticed that he became psycho after certain drinks - being sceptical about colour related behavior I started to read the labels whenever he went truly demented and psychotic - of course you can guess what I found - 102 At the time I had no idea that other people knew it was bad - I just thought I had the only child in the world who reacted to yellow colour - particularly as the popular wisdom of the day all said that red colour was the problem. So for the last 2 years I have avoided 102 - this helped a bit - but not totally.

The local health centre's counsellor visited the school and reported that his behavior was Oppositional Defiant - first time I had ever heard of it. The solution was to maximise his 'good interactions' - so once again no real help, and leaving it up to me to be a better parent.

Alex started school at the same child-centred preschool/school last year - he had a reasonably good year but was chronically sick - temperatures, stomach aches, head aches. However as he is so hyperactive, he often didn't realise he was sick, and I had to fight to get doctors to look at him. For example, I took him to hospital with severe asthma/croup - however as he was running around casualty making chicken noises he was not seen to as a priority case - when they finally looked at him, his oxygen levels were dangerously low and he was gasping for breath.

Another time we sat in a waiting room, left till last as he was jumping on chairs (and apparently well) - when he was finally seen the doctor couldn't believe he was racing around - his temperature was 41 and he had acute tonsillitis and a ear infection. He also had a severe salmonella infection last year and was losing considerable quantities of blood, but because of his high energy levels I was told it was just gastro and I was exaggerating his symptoms - it was finally diagnosed as salmonella and he had 2 weeks off recovering - I now know that when Alex is sick I have to force doctors to look for the worst. While I know he is ill, to anyone else he seems too full of beans to be sick - time and time again the doctors have been surprised when some odd illness turns up (ie scarlet fever, pneumonia, bronchiolitis, to name just a few)

At the end of last year I took Alex to yet another pediatrician - this time about his health - after a year of infections and unexplained temperatures I was thinking that there was something seriously wrong - he took his medical history and noted his pallor, and dark circles under his eyes - and pronounced food intolerance!!!

In December I started him on the diet given to me by this doctor - we removed milk, honey, colours and preservatives - and were told he could eat fruit, vegies and only cold pressed oil.

So - no result - if anything he became worse. While I thank this doctor for pointing me in the direction of food intolerance, his diet did nothing to help. A family friend recommended your cookbook to my mum. Since then I have spent the holidays reading Fed Up, and the cookbook and going failsafe.

We have cut out diary, amines, salicylates, and all the artificial additives, colours, preservatives etc. My mum has been a fantastic support. She is making all the 'extras' ie: jams, mayonaise, biscuits etc. Without her I couldn't have achieved so much. She also rings up food companies and asks them to clarify what their ingredients are, and what type of oil they are using! We haven't taken out gluten yet - not sure whether it is necessary.

And Alex? It has taken a while, but by the end of the holiday he was so much better. He was able to play consistently with children without it erupting into a major argument. Parents and friends have noticed the difference. I have also noticed that he is now able to be disciplined. He can hear what I am saying and understands when his behavior is wrong and I can now win an argument.

Last week was the first week back at school - first day was fantastic and I received lots of comment about how he changed. Then he started cheating and eating roll ups, muesli bars, chocolate cake and sweets from his friends - by the weekend he was making repetitive noises, chatting constantly, being selfish, crying and was unable to control himself. He visited a friend on the weekend, who had seen him a week before in his good phase, and she couldn't believe the difference - she is now a convert to the idea of food intolerance. In her words it is like he is on a drug trip, and we all just have to wait for him to come 'down'.

So we are back trying to get him adhering to his diet again - he says he wants to - I just have to wait and see. I want to get him back to the point where we can try some controlled challenges!

And the rest of the family? None of us are totally failsafe yet, and are all cheating when we are out, but I believe we all have symptoms that warrant the diet. My 9 yr old daughter is incredibly artistic, but unable to read, and has temper tantrums, I suffer migraines, mood swings, arthritis and occasional depression. Interestingly, my daughter did some market research for a new hyper flavoured snack food a few weeks ago. She came home in an uncontrollable rage to the point that she was throwing herself around the house kicking furniture etc. I have never seen her like that before - and just think, those snacks are about to do that to all our kids - it's criminal. - reader, Sydney
