Grrr just lost my reply how frustrating...
Well as you clearly know so much already then I'm sure you don't need my opinions.
But if the baby is bates jones it is linked to both sides of the family.
Now I know children who have been negatively effected by mistaken naming. Now these people may be dumb but it doesn't change the fact that comments will be made.
A colleague of mine had a son before marriage, since getting marriage mum, husband and siblings all have one name. They have not changed first sons name as they believe you can not hide who you are and brush past under carpet and make it something else. Child is happy as they are special and understands why their name is different. This child has very little snide comments made.
On contrast a friend of mine has had to endure a lifetime of whispering, snide comments about now who's your dad, just how are you related to x y z, now hes not you real father is he, isn't you father x etc etc
So these people are awful and I do not condone their behaviour but I am wise enough to realise that that even the best intentions can go horribly wrong due to interfering nasty people that do live in this society to.
Naturally as you know so much I am sure you have considered this already and don't need me to point out something so obvious so I'll go back over to the dumb corner with my views and hope that your child is one of the lucky ones who miss the interfering busybody section of society entirely
