Please show me the rule that allows the TD to ban toddlers/babies from the tourney.
Rules 3.3A and 3.3B of the PDGA Competition Manual empower TDs of PDGA sanctioned events to disqualify players for a wide range of actions.
There are PDGA rule disallowing dogs, smoking, alcohol, and tank tops, but no rule preventing a player from having a child along with him during a tournament.
While the PDGA does not explicitly ban babies, rule 3.3B states, "Actions that are in violation of this conduct include but are not limited to:" before listing examples of conduct deemed unprofessional and unsportsmanlike and thus grounds for disqualification.
The phrase "... included but not limited to:" brings discretion and subjectivity into the interpretation of the rules, like with almost any rule book or written laws that govern human activity.
Of course, I'm not an attorney, but I bet the attorneys who wrote the PDGA Rule Book inserted that open-ended phrase, "... included but not limited to:", specifically because the PDGA wanted to grant TDs the power to disqualify any player for a wide range of behaviors.
The last thing the PDGA bosses want is for random players around the world to kick up to them disputed decisions by TDs of obscure C-Tiers in Anytown, USA - that's why they included rule 3.3B. They have more important things to do with their time.
I'll add the caveat that in a non-sanctioned tournament, the TD can obviously do whatever he wants.
Totally agree that TDs of unscanctioned events can do whatever they want. But I would argue that rule 3.3 allows TDs of PDGA events to do whatever they want too, at least when it comes to interpreting the rule book.
Of course interpretation of these open-ended rules usually comes down to application of common sense, generally accepted common behavior and customs. So, if a TD disqualified a player for toting a baby around during tournament play, I can't believe the TD would encounter any resistance from many other players or from the PDGA bosses. In fact, I think the PDGA would applaud the TD for doing so.
Of the TDs I know in SoCal, almost all would, if faced with this ridiculous and highly improbable hypothetical scenario, either plead with the baby toter to do something responsible with the baby that didn't include toting it around the course during a round or offer the baby toter their money back and disqualify them.
