I’m not a fan of the title, it sounds a bit odd. (Control?) I am assuming from the title that this is something more than simple toilet training. Regardless, even if this method is still valid, the age of the book puts the information in question. I have no idea if bedwetting control is some type of special circumstance from regular toilet training. I would say that since it has implications for health, it should be treated as such. Time to flush this one.
