A year is a good time for a horse to learn how to tie, with quick release. I'd use the method of running the line through a ring so you can add and relieve pressure to teach them to stand tied.
As for teaching him to stand untied...
1 year they have really short attention spans, it's not impossible- but you need patients. The way I do it is draw a box around my horse in the footing, assuming your in an arena, otherwise you'll just need to imagine it. Stand in front of the horse and look squarely at their feet, imagine their feet like cinder blocks and say "Stand" firmly. Stay still for just a moment, if they move just place them back in their spot, if they move alot - like walk away completely - make them yield a few diferent parts then place them back in their box and stand again. Repeat this until you can back away, then again until you can circle them without concern. If they move simply replace them and say "stand". It takes patients, good luck! Remember with babies to do frequent, short lessons, 5-10 minutes a couple times a day if you can.
Good luck, welcome to the forum! We love pics, specially babies :3
