There are a lot of methods and a lot of opinions when it comes to potty training, and all of that played out on social media after a picture went viral of a mom sitting her child on a portable potty in the aisle of an airplane. Someone posted it on the Passenger Shaming Instagram. Most people were totally against it, calling it everything from disgusting to outrageous. But others — moms in particular — jumped to the woman’s defense. They say potty training is going great at home and then you venture out. The kid has to go at that moment, so what do you do?
