Any good tips for building confidence in jumping??

... and not for me but for my 13 year old gelding (maybe a little bit for me but mostly my big baby).
Right now we're jumping 1-2 ft natural jumps and he's very shy about them. I've had him for about 3 years and it hasn't gotten better. My previous horse was very forward, loved to jump and did everything at speed so I'm not exactly clued in to what to do with a horse who doesn't particularly like to jump. We're not shooting for GP but I'd just really like for him to think it's fun! Any good exercises out there that would spruce up our life?

Its important not to overfence him - if he has a stablemate that likes to jump go out as a pair and have the other horse as a lead , your boy should follow the other horse - it should make him less wary of jumping if he is following someone else.

I agree with Nutty saddler. That really works, believe me! I rode a lesson horse named Izzy who hated jumping! However we would put him behind a confident jumper and he'd be like "Oh maybe its not that bad?" He was the sweetest horse he just needed a little push and confidence. Oh and you should give lots and lots of praise once he does go over, just to reassure him that thats how you want it done.
