I can't really help you with the weaning because I did not breastfeed.
Will she not drink breastmilk from a bottle? You mentioned she will not drink milk .......do you mean whole cow's milk which she shouldn't really have until about 12 months of age, but like I said you could offer her breastmilk in a bottle, soy milk or formula (check with her ped.).
Drinking juice from a sippy cup all day may fill her up so that she is not getting the proper nutrients she needs from solids/and breastmilk or formula. She is probably so used to the sweet taste of the juice that milk is just not appealing to her.
I started my son on whole cow's milk at around 12 months and around 11 months offered him yogurt (Minigoes) which he loved.
Now at 2 yrs old he loves milk because I never made juice an option, only for a treat once in a while and when I did it was unsweetened and mixed with water. In between meals I only give him water so he does not fill up and he eats his meals, and with meals he gets milk, and once in a while or for a snack before bed I offer him unwsweetened apple jc or orange jc fortified with calcium.
If your daughter is eating enough in the day, and breastfeeding right before bed she shouldn't really wake up hungry........maybe it's just a comfort thing for her and she really just wants you. You need your sleep to so maybe just try letting her cry for a few minutes before going to her.
I'm not sure what else to suggest.
