This video has a lot of "common sense" potty training tips, but I really the the one about bringing along a portable potty where ever you go. A lot of kids are incredibly afraid of the sound of commercial flush toilets. (Those things are LOUD!) Even my four year old is still terrified of them and she's been potty trained since 20 months old. Having a familiar portable toilet can ease anxiety and make a child less likely to fight a trip to the bathroom.
A good selection of travel potties can be found on Amazon.com. My favorite is the On the Go Potty because it fits in a diaper bag. (See below)
