Yet to read all the thread...it is very long !!! So I might come back tonight with further comments.
Re. Nursing an older child at a wedding. If I needed to I would. If a non-nursing child needed a dummy or bottle of milk no one would bat an eye, breastfeeding is the original source of milk and the model for a dummy and should be given the same lack of interest by others.
Of course a bride could ask any child not to be comforted during her wedding breakfast, that is her right as the host. Equally I would not attend the wedding of someone who wanted to exercise such control over the needs of my children.
I would be especially upset if the reason given was other guests hangups. One of the major reasons that nursing in public is so frowned upon, is the rarity of nursing mothers in todays society.
Watching my own parents and inlaws behaviour improve over the last nearly 3 years. Has proven to me that education and refusing to pander to other peoples issues is better for them in the long run. Should my sister or SIL wish to breastfeed, I have left a legacy of better attitudes to nursing in my own family.
Not that I nurse to make a point, far from it. It is just a normal way to interact with my children, where ever we happen to me, for both my 11 month old and my 2.11 year old.
When I balance up the needs of adults and young children, the children needs must prevail. Especially as it is so easy for adults not to be offended. They can do what I do when faced with people I don't wish to look at, I choose another direction to look in...very simple.
