In around Oct last year, my 8 year old son, who is usually dry at night, started wetting his bed. He wet it every night for over 2 months. During this same time, his twin sister – who has never been dry at night, went from wetting her bed once a night to wetting at least twice a night. Even their 3 year old brother, who was occasionally dry, stopped having any dry nights.

The first think I started to think about was what had changed in our diet, since it was something affecting all 3 of them. I was Googling away when I happened to come across your Food Intolerance Network site and the link between Calcium Propionate and bedwetting. I found a "what's in your bread" website (since we were in the car on a journey up to Scotland, and not at home) and discovered that the "healthy", Warburtons Seeded Batch Loaf which we had switched to about 2 months before contains 282. I have not used it, or any of the bagels or wraps (all with 282) we used to buy again and my son has not wet his bed once since then – apart from last Monday night. The children went back to school this week and go to an after school club on Mondays where they get sandwiches for a snack. I called the manager to find out what kind of bread they use – and sure enough, it is a long-life bread with 282. I explained all the dangers of this particular preservative to her and she was most willing to switch to a safer brand in future! – Michelle, UK
