Is it just #2? Will he urinate in the bowl? Did he have a bad experience, ie: almost falling in? The next time YOU go potty have him sit on his potty near you. First thing in the AM sit him on his potty. Get to know when he usually goes and have him sit on the potty around those times. I wouldn't put the pullups on him, get rid of them! Does his dad help with this situation? Be sure to make a BIG deal anytime he attempts to sit on the potty. Clapping hands and all. Good Luck Oh and about being scared of everything, what type of movies, videos, books, etc is he exposed to? My 6 year old niece is afraid of everything too, but she is allowed to watch movies like Freddy Cruger.....very bad idea!
