Jimmy—Your country extension indicates that you are from South Africa.  Neither of your issues should prevent your being successful with the Soiling Solutions Protocol to eliminate soiling early on with the carefully timed use of short sits escalating to suppositories and enemas as they may be required.  This should lead to your son to taking over his own inherent voiding reflex even though implementation and response may be slower because of his ADHD.  Rather than going into any extensive detail here, please read on and you will gain a better idea about the SS protocol and the theory behind its success.  Also, I will attach in a separate email my recent medical journal article on the history and rationale for the SS Protocol.
