considering you haven’t defined public, and don’t seem like you want to define public, yeah i’m going to say that’s probably rude.

How exactly do you think someone changes a diaper at a park?

Not all parks have restrooms. Not all parks with restrooms have working restrooms. Not everyone drives their car everywhere.

I suppose next you’ll tell me that people should only take their babies to parks that have working and open restrooms or drive to a park.
