For weaning A, I had the best luck when I latched her initially with the shield on, so she had a couple minutes of milk and then wasn’t so hangry. Then unlatch, quickly pop off the shield and try to relatch her. Try again and relatch if it really hurts or is a bad latch. It may take some trying, and some pain on your side (sorry, nips), but just keep trying! If she’s successfully latching the one side then you should be able to clue her in to the other side eventually too. Teeth are not awesome if you nurse lol. But if you have a good latch, you won’t feel the teeth unless they bite you. That only happened a couple times to me because I would unlatch A when she bit me and make her wait a minute before trying again. They will hopefully figure out you won’t feed them if they are going to bite you because it hurts mom. Edit: although A was bad at chewing on my nips sometimes with her gums (before teeth), so maybe I was partly desensitized to the chomping and partly had trained her not to do that by the time teeth came along.
