Hi J.,
I think what you are describing is pretty normal, especially if she sleeps with you in your bed (which is probably more normal than we think!). My son is 26 months and also slept in our bed. I very gradually weaned him from night breastfeedings from about 18 to 22 months, by gradually prolonging when he would get breastfed (ie. not breastfeeding til after 12, then when comfortable with that not til after 1, etc) He fought this very hard, but I felt that at least he knew we were there for him and he was at an age where he could understand, mama needs her sleep too (mama go night-night I would tell him). Maybe when you feel you and her are ready you could try something similar, like gradually weaning her from being rocked back to sleep, by substituting your voice or a rub on her back or snuggling instead of rocking.
It felt sometimes like a very slow process to my husband and I, but I could never bring myself to do the "quick" cry it out method by themselves. At least when they are next to you, your child will not feel alone or abandoned.
By the way, my little guy now has a toddler bed pulled right up against our bed and sleeps there all night (sometimes he sleeps thru the night - seems like a miracle to me whenever that happens, lol). Sometimes he wakes 1 or 2 times and I just scoot over and we snuggle for a few minutes til he falls back asleep. And just like before, I know that eventually he will not need to snuggle with mama to go back to sleep. I just have to remind myself, lol, that it is a slow process and that if I let him do it in his own time we will have the most success.
good luck,
M.
