DD is 4 mos. old. After a couple of months of pain-free, easy nursing, it's starting to really hurt again. Although there are no actual teeth yet, I believe she is in the throes of teething. When she nurses now she is often gumming my nipples really hard---ouch! I take her off and try to put her back on again when it's bad, but that means we're popping on and off again a lot sometimes (with milk flying everywhere!). Any suggestions for coping with this, as I foresee this being a looooong road?
