We started the strict elimination diet a year ago and have been following it since then for my 6 year old son because he was diagnosed with encopresis, given drugs that didn't work and was soiling his pants every day at school. Horrible. When we started the diet we had amazing success. He started pooing in the toilet every day and the pants soiling stopped almost immediately. The only time that this happened again for all of last year was when he was reacting to something through challenges or by something that snuck into his diet.  – Toni
