I don't know if I would've used the term "chicken and egg" to describe this situation, but I will advise the researchers of an observation of mine culled from long years of experience: adults who are constipated also often refuse to use the potty!!!
A lot of children who refuse to poop in the toilet during training are also constipated—but it's not clear what comes first, the constipation or the training problems. Researchers at the University of Pennsylvania tried to resolve this chicken-or-the-egg debate.
