My son is 8 yrs.old and we have been using Pacific International for about a year and a half with limited success. Before this commitment, we had used another type of alarm (similar to potty pager) for about 1 1/2 years with no success. He is a very deep sleeper. Just as we were about to drop out of P.I., we decided to stop the milk that he enjoys with dinner and we are curtailing liquids before bed. This sometimes results in about 5 dry nights per week. P.I. wants the child to drink a quantity of water before bed, teaching them to awaken when necessary, but this didn't work for us in he last year and a half. I do allow 2-3 oz. of water before bed while brushing teeth, but I don't push it. I hope something works soon. I'll keep you posted regarding this programs success rate for us.
