Aw, I feel your pain!
Just remember that this is just a stage and it too will pass.
I think the number one most important thing is to not get outwardly frustrated with her, "she's just a baby".
Mine is still nursing at 17 mos. (though I originally "anticipated" stopping 6 mos... then later, at a year) and I've found it, yes, trying at times, but in the long run sooo worth it.
I mean, come on now, the baby doesn't know what it means to be six months old (haha, or "more independant" at a year, lol~) I just have responded to what works for us, and that's all you can do.
After she starts taking in more solids, you'll start to get some boob-production relief. My thoughts on the solids are to begin making mealtime a routine 3x a day, breakfast, lunch, dinner and trying to keep the times consistent. Don't just give her jarred foods but really some good stuff like avocado and fresh (but ripe)mushed up banana. Browse the site wholesomebabyfoods.com for some ideas.
Take cues from her and, more importantly, don't fret too much that she is getting enough. I think it's very instinctual to do so-- I have been there-- so many moms fret-- but really, she is not going to starve and when going through a bout of teething just may not have the best appetite. Excessive salivation can also reduce appetite.
Begin setting up some eating routines for her and that way her body will come to expect food at those times.
I remember going through a lot of Hyland's teething tablets and Tylenol at this age- it's very trying to be sleep deprived and have a little clingy fussy one!
I also agree (not sure at what age is ok) but Motrin is more effective (I learned later) for teething.
Also, take good care of yourself. Make sure you are eating well and drinking enough water (of course ;D)
Give kudos to yourself for being a nursing mom and enduring this long. I'm telling you, if you stick it out through these hard times, I think it will benefit her a lot.
You mention the pain-- are you actually getting injured by her teeth?
That has happened to me, and it's very important to treat that, maybe with some prescription nipple cream (call your gyno).
Try hanging with some other nursing moms so you can get their support. That is so important.
Do you have something that can keep her occupied? The "rainforest jumperoo" did us wonders- others, an exersaucer, that sorta thing.
