I have a 2 year old son whose diet I have recently changed due to the behavioural problems that we were experiencing with him. My son was a big bread eater. While I was pregnant with him I was eating 10 slices of bread a day with 282 bread preservative and by the age of 18 months my son was eating the same amount. He was always a very difficult sleeper and has been having seizures since he was 18 months old. Since changing his diet to preservative free bread , he has gone from a monster to a reasonably placid child, he sleeps well, and his seizures have improved remarkably. Update: in the last 6 months he has had only three seizures. – by email, NSW
