Re: Itchy/sore nipples with poor latch
When a soreness issue crops up in a mama who has enjoyed a long trouble-free period of nursing, I always think "thrush or teething". In your case, I'm torn. The itchiness and white tongue make me lean towards thrush, but the pinching latch and biting make me think teething. Can you get in to see your doc? Having someone take a good look in baby's mouth might help rule thrush in/out.
