I'm only breast feeding twice a day. I think my supply is dwindling. She eats for a very short time, starts to play and then bites me. If the biting was happening while she was still eating well I would get past it but i either need to give a small bottle after or soon after, so clearly she is not getting enough.
I stopped nursing and only pumped when I couldn't stand it anymore, drank tons of caffeine and took sudafed, and wore a tight sports bra for about a week.
I'm not sure this is the healthiest way, but I went from being her only food supply to no engorgement in under a week.
Towards the end, I would set up to nurse with a bottle of cow's milk right beside me since she needed more than I was providing at that point. One day she just reached straight for the milk and that was it. I had no engorgement issues since my supply had already dwindled.
