I think I might have posted before on your other thread...
Just hang in there. DD has been doing this more or less constantly from about 15 mos and is now 23 mos. She is down to 1 or 2 nursings a day due to this problem. I really wish there were more answers. I totally know how you feel!
I understand advice to unlatch when biting, but if you are like me, this is not really biting as much as a bad latch where the child opens wide, but then clenches and grips with the jaw and teeth instead of letting the suck provide the closing of the mouth and using the lips to hold on. That is *very* hard to explain to a baby/toddler!
The only advice I got after consulting 3 different LCs and LLL was to get some dental wax and put it on her teeth prior to nursing so it would lessen the painful indent of her teeth. DD would never go for that!
On our own, we finally came up with a little system that helps sometimes. I will have dd suck on my finger first and tell her to hold on with her lips not her teeth. Put index finger in with pad of finger back on the soft palate (this is actually a suck exercise used to help establish nursing with preemies or tiny babies or others having trouble). B4 doing this I explained that she needs to hold mommy with her lips not her teeth. And I also demonstrated gently the difference on her finger in my mouth - using my teeth just enough to be a bit uncomfy but not to hurt her (don't worry, she still asks me to show her so it didnt' hurt).
That's the only thing we have found success with. I know it's related to teething. The last of dd's 4 eye teeth are just coming in so I'm hoping we will have some relief at last and the 4 yr molars won't be a pain too. (no pun intended). Maybe some nipple soothing stuff from Earth Mama Angel Baby would help - i keep meaning to order it.
I understand wanting to wean!! Oh, do I understand! Can't tell you how many times I swore that was the last time. What's worked for us is to tell her if it hurts that we are all done and say happily "Ok, we will try again later!" This doesn't get the best reaction at first, but if you say it cheerily, eventually (if she's like my dd) she will be ok with it and even say "tie gain yater!" I will even tell her before we nurse. "We open wide, nurse gently, and if it hurts mommy... try again later" the last part always said with a big smile to let her know it's ok.
We have had to night wean (it was much worse at night) so she only nurses right b4 bed and not during the night. For us, having a bedtime snack of something filling - oatmeal, lots of cheeriois etc - some sort of carb is helpful. And for a short while we had to give her a snack of mashed banana or applesauce (something super quick and no chewing involved) in the wee hrs of the Am. Just had her sit up and fed it to her quick in the dark.
Instead of weaning completely, think of cutting back - and try not to feel guilty (like I often do), but instead be grateful that you can still give her the wonderful gift of your milk even through hardship. Some is always better than none.
I wish Mothering would do an article on this o- maybe they could find better resources than I have been able to.
Good luck!
Good luck
