My little one also ate twice a night until about 6 months old. I didnt get rid of the 12 oclock feeding until she was only taking 2 or 3 oz. At that point I let her fuss and then she was fine after a night or two. I dont think she would be eating if she wasnt hungry. Have you tried doing other things like just repositioning or rocking before offering the bottle? I dont think you are doing anything wrong, babies are just different and when you feel she is ready, you can wean her from those feedings. Dont worry:)
