DD3 has assthma and uses a nebulizer. We took a trip last year to Mexico, and having it in my carryon was a nightmare with security. Has anyone had any problems lately? Our flight is 2hrs long. It doesn't have a battery adaptor, so I wouldn't be able to use it in flight anyways. Should it go in my checked luggage? We're currently only using it for attacks. 1 attack per 10 days is our average. Your advice is appreciated.
