When my baby teeths and starts to bite on my wife nipples, it creates a situation of soreness and pain. what are the possible solutions to address my baby's need to bite things?

Agree with mummy Jacinthia. I would scold first. If it doesn't work I will yelp in pain loudly and pretend cries "baby bite mummy, mummy pain pain" and observe baby's reaction. Otherwise, I would just tap with 2 fingers on baby's cheek, hard enough to give pain. These methods work for me. Otherwise, cold teether first then latch.
