Holly B had an AWESOME answer!
For me, I only got bit a few of times, and I don't think any of them were on purpose. If I didn't hold him right, then once in a while his head would fall back while he started to fall asleep, then he'd try to "grab" me again with his teeth. OUCH! If this is your situation, think about how you're holding her and whether her head can fall away the wrong way. As long as you are properly supporting her head, you’ll do okay. I was able to keep nursing to 18 months, or more importantly to your situation, about 16 teeth.
Now for the BAD news! If your nibble is very tender and nursing HURTS immensely, KEEP DOING IT! If your breast becomes red and hot, and/or you start running a fever, contact your doctor. Mastitis- an infection of the milk duct, is VERY common after a trauma such as this. It happened to me after the first time that my son bite me. Unfortunately, to get rid of it you must nurse more, which is EXCRUCIATING (makes nursing that first week after birth feel like a game of pat-E-cake), and take an antibiotic.
You’ll do fine! Just keep Holly’s advice in mind if she thinks it’s a game, and how you hold her if she’s nodding off. ~J.
