Children are naturally curious. That’s why they ask so many questions. They like to know how things work, especially their body and they are fascinated by bodily products like spit, pee and poop. It's no wonder that preschool children enjoy “potty talk”.
Unfortunately, most parents discourage talking about poop. However, learning about poop and being allowed to engage in (good) potty talk are very important in the treatment of childhood constipation. Children four years of age and older need to know and be encouraged to talk about things like where and how their body makes poop, what causes their poop to get hard (and hurt!) and how poop medicine works.
Feeling comfortable using words like "poop" and talking clearly about related questions and concerns with parents also often results in more appropriate use of that language in public. As this kind of talk becomes more commonplace, it becomes less interesting or funny to the child and he/she will start to use it less in inappropriate situations.
One of my early treatment objectives is that when a child is sitting on the toilet to poop, he or she will be able to imagine where their poop is waiting to come out (“poop collector” or rectum) and about what they need to do to help it come out (push). See Chapter 12 in my book for detailed instructions on how to educate children about poop and constipation.
