I have enjoyed reading the experiences here very much.
When I hear a mother's concerns about baby's father feeling like the "odd man out", due to mother and baby's nursing relationship, I think of the latest issue of New Beginnings. There was a section with a mother's question about her stay-at-home husband feeling dejected b/c when she returned home at day's end, all the baby wanted was to be close to mother. He blamed the nursing relationship on that desire for closeness with mom that baby exhibited. There were a variety of ideas and experiences shared by many mothers in answer to the mother's question. If you've access to the latest copy, perhaps that's something you may find interesting?
Here is a link to New Beginnings articles that relate to Fathers and Breastfeeding:

For any research-a-holics out there, the LLLI Center for Breastfeeding Information has a page of references about Spousal Support for Breastfeeding! Lots of reading here...
Each person's situation, marriage, child, etc. is completely unique. I find it reassuring to find such support and encouragement being shared by mothers of varying situations here.
