I agree with Allison on this one, I always start my horses SMALL and then its small+fillers, then higher, then higher+fillers. So a 1'6 oxer, then move on to adding fillers, such as flowers, then raise it to 2' but no flowers, then add the flowers in. Slowly work towards your goal, but only move on when the horse is comfortable. I have a pony that will jump almost anything, even though he's green, as long as im riding. But a girl who rides him who is a little nervous about jumping often psyches herself out before the fence so hell stop the first go around and then go over it from there. So make sure YOUR not nervous about it because that is only going to make the stopping worse. Set up a small course, like 1'6, that's very easy to walk over if needed! Set up oxers, fans, verticals, cross rails, planks, gates, add fillers, etc but do it all at this height. Make it funky! Then slowly raise the height after he's fine jumping all of that goofy "scary" stuff at that height. Hell gain confidence and start jumping the first time around, you just have to take the time to make things a piece of cake for him so that he can gain the confidence needed.
