If you are having second thoughts, then maybe it's not time to totally wean, but change the schedule. Work on weaning her off of a session in the middle of the night or first thing in the AM, for example. Going cold turkey is often harder on you and your child, so start to nudge her away from some of the sessions and distract her and make it a different experience. Once you are no longer nursing some of the time, you may find that it works for you, or that it works for you both to continue the gentle slide into not nursing anymore. My DD nursed only at bedtime for most of a year and then slowly that was gone, too. So I'm suggesting that since you are torn, find a medium that works for you right now.
FYI, I nursed DD til 2.5 and she still isn't a big milk drinker, but neither am I. We get calcium from other sources. If she's not a fan of milk, train her to use a cup with other liquids and give her other sources of dairy.
