Honestly Becky, if it were me I'd forget about putting the bridle on for now. Unfortunately us humans can be rather too goal oriented and it would be a mistake IMO to focus on the goal of getting a bridle on, when perhaps a more valuable, and practical goal would be to overcome his fear of having his ears touched. I'd suggest the advance/retreat method of gently getting him comfortable with you brushing him on is neck, then near the top of his neck, then on his forehead if thats not an issue - and every time, always backing off
before you get to the stress place. Effectively, his reward for accepting what you are doing is backing off and stopping
before he gets stressed and reacts, with every session taking you closer as his tolerance and trust build up - how fast this progresses is decided by his tolerance, but its critical that you always back off when he is
good and not when he is reacting negatively. If you have advanced a little and he fidgets then you
must hold your hand there until he stops, but you must remove it the second he stops pulling away. So reward for standing still is remove your hand, consequence of pulling away is you don't back off. That doesn't mean chasing/harrassing - you must set things up so you
both can succede. Does any of that make sense? I think Sarah Weston is back from her African 'jaunt' soon so it would probably be money well spent to get a visit from her if you are local to the forest. Or if not, check out the Intelligent Horsemanship website for an approved RA in your area who will quickly help you sort the head problem. Sort the head/ear issue and the bridling problem will vanish too!
Oh forgot to mention the obvious, which is check there is no physical problem such as ear mites, aural plaque (like a fungal infection in the ears) etc. Even teething problems can cause ear sensitivity at certain ages.
