My son still nurses at least once a night a few times a week, and I'm OK with that. It doesn't sound like she is eating much protein, have you tried introducing chicken, beef, turkey, etc? E is almost 11 months, gets three meals a day and has since 8 months. Two meals (lunch & dinner) consist of a protein, fruit and veggie. We also introduced 'snacks' in the last few weeks. He loves yogurt (I give him greek yogurt) and fruit as a snack. I would keep offering solids, but it sounds like it is time to introduce different foods and offer a variety of fruits/veggies/proteins.
E still has really bad nights, usually when he is teething. He doesn't want to nurse though, if he does it is just for comfort. Ibuprofen works amazing for E when he is having teething pain.
