Have painful crack in one side that isn't healing, it was improving but seems to have got worse again. Had it for over three weeks now. Latch is mostly ok bit dd is having to relearn it a bit since her Tongue tie snip on tues. Anyhow tonight it got so bad I had to stop her feeding on that side- so am desperately looking for something to heal it fast! Have seen these cups mentioned on here before but wanted to check them out before forking out as they are bloody expensive!
