Weaning….

Okay, I need some advice on weaning my daughter. She is 15 months currently and doing really well. I’m just to the point that I’m ready to start. She was nursing every two hours all day and night….which has been hard. She has a really high metabolism that is genetic from her dad. I’ve gotten her to the point of nursing every four hours during the day if I give her plenty of solids and keep her distracted, but I don’t know what to do at night. My doc mentioned it could be soothing issues, but she goes to sleep in her crib by herself at night. Wakes to eat, throws a huge tantrum and won’t stay asleep if I don’t feed her. Will feed for her normal five minutes, pull off when done, I set her in her crib, and she rolls over and goes back to sleep. Then 2-3 hours later she is awake again asking to eat. I told doc all this and he thinks she really is just hungry! I’ve tried the few things he recommended. First pedisure…won’t drink it, than oatmeal…ate it twice now won’t, switched to a later dinner…still up every two hours. I need consistent sleep. And she recently started biting (on accident) and drew blood/left scabs on my breasts. How do I wean a baby who loves to nurse?!?!? Even if I could just get her to every four hours at night, I would be so happy! My husband is really busy with work right now so I don’t want to make her just tantrum because he needs his sleep too….help??
