My son just started potty training today and I just realized that we are going to be flying from NYC to LA in about a month. How do you handle flights with toddlers who are new to the whole bathroom thing? The idea of him actually sitting or touching anything in an airplane lavatory almost makes me want to throw up a little in my mouth. But I’ve heard once they’re potty trained you’re not supposed to go back to diapers. So how do people handle this? Also what if he naps on the flight?
