My son is like that. He's 15 months now and it's a little better than when he was 10 months. You can't change your child's personality. She will outgrow the need to nurse, and will sleep better, eventually. I know that's not what you want to hear!

There's no such thing as a "human pacifier". One of the primary functions of breasts is to provide emotional comfort - nursing is not just about food. The reason pacifiers exist is to replace mothers - they are plastic nipples. That said, I would have used one too had my son taken it!
Recently, I've been able to avoid the constant nursing at night by just laying on my stomach. When he wakes up every 45-90 minutes, as always, he will whine a bit, stand up in bed, grab my back, flop around, roll sideways down my back, and then pass back out. I know he's actually hungry when the whining escalates and he doesn't get quiet after a minute or so, and then we nurse laying down and he rolls over and falls asleep. This only works if I lay on my stomach and make my breasts completely inaccessible. And it's only worked in the last 2 weeks.
I understand completely. I was just complaining about DS' crappy sleeping at a LLL meeting today, and the consensus there seemed to be that some kids are just bad sleepers (by which I mean they wake up a lot, don't need as much sleep as we'd like them to get, need a lot of parental attention/action to get back to sleep). And they always grow out of it. As I type this, I can hear him starting to stir on the monitor. He's only been asleep for an hour, and he's about to wake up.
Also, if she has only ever fallen asleep nursing, she may believe she
needs it to sleep. If that's the condition with which she always falls asleep, then it makes sense that every time she wakes up as she enters the lighter stage of each sleep cycle, she feels alarmed because she's missing the condition she thinks she needs to sleep. You can help her learn that she doesn't NEED to nurse to sleep. Maybe do naps another way - car, stroller, carrier walk, etc. And spend a few nights trying to get her to sleep without nursing. We did that 2 weeks ago and it was hard for the first 2 nights, but now it's pretty easy. I'm not talking CIO. DH and I were both with DS, and I would nurse, but in a position that made it impossible for him to stay latched once he fell asleep. He would get frustrated, fuss, I would hold him, we did massage, singing, bouncing, dancing, music, told a story, etc. Everything. He was pissed off at the change in circumstances those first two nights, but he quickly got used to it, and now he falls asleep without nursing pretty easily. We nurse first, then I hold him and lay him down, he gets up, repeat 20 times until he stays, flails around and falls asleep.
Hang in there!
