I remember in my second trimester I had a very vivid dream that I was nursing two baby bears and they kept trying to bite my nipples! It was extremely unpleasant but when I woke up and discussed it with my doctor, he assured me that it was normal and that I may be having some fears associated with nursing. After thinking about it more, I realized he was right! I found a good friend who was a "nursing expert" and unloaded my fears to her. She was so helpful in calming me and helping me come to terms with my anxieties about the postpartum experiences.
