When you start to use potty for your kids, don't forget patience, patience is a virtue, patience is the key.

Let them run around naked without pants to encouraged them to use the potty, after that let them to go sans pants, after they mastered naked-potty use, let them to wear them the underwear then the pants.

We worked our way up to clothes (first just underwear, then eventually pants). This method was extremely painless -- very few accidents or setbacks. 

Turn the potty into a game, example: put three cheerios in the potty and told your kid to aim them, if he did it right, tell him go to pick out a prize from a bag of goodies.

Use the funny white lie with you kids, tell him that when he flush. this will goes out to the sea to feed the fish, because the fish have nothing to eat, your son being sensitive, and will make anything to feed the fish.

every time you use the potty. decorate their outfits with the stickers. At the end of the day the kids will collect alot number of stickers, it will encourage him to use the potty more.

The kids may be feel terrified in public restrooms. So put a Post-It note over the sensor and it will prevent the toilet from auto-flushing. After she's all done, wiped, and left the stall, you can remove the paper to let the toilet flush.
