Like everyone else said, gradually taking away a feeding is the best to do if baby is under 12 months old. I nursed my kids until well after a year each. They just cut down alot by themselves once they hit a year. Too busy doing other things. Your body will produce less milk after a year, becasue they don't drink as much each time, so when it's time to stop there's no problems. At a year, my kids would be nursing about 6 times a day (snack time, right after eating meals). So I just stopped nursing them after meals - which cut out 3 a day. And I never noticed. No discomfort or engorgment or anything. My son nursed 1-2 times a day for another few months. My daughter continued for another 6-7 months with those 1-2 times a day. Basically one day I decided to stop offering - the "don't offer, don't refuse" method. My son stopped asking within a few days, my daughter a few months.
But anyways... if you continue to nurse until a year, you don't have to worry about any discomfort or anything when you stop, even if you drop 2-3 feedings in a day. So just continue what you're doing until the birthday and then wean and you'll be done within a couple weeks. After 1-2 days of not nursing, you're body will just stop producing milk. No extra help needed.
Just as a side note... most 8-10 month olds go through a stage where they don't seem interested in breastfeeding. They are just too busy wanting to explore the new world that suddenly opened up to them since this the time most are crawling, cruising or walking. For most it's just a stage and if you continue to offer to breastfeed, most will continue happily after getting through this stage. If you want to continue to breastfeed past a year (world health organization says 2 years is best) just continue to offer and she'll probably still be interested in a few weeks. If you want to stop, that's fine, too of course. Just don't feel like you "have" to stop at a year.
