I have 4 DD, my youngest is 1 next month.
My MIL won't use her name, just calls her baby she says it is impossible to pronounce (it isn't) in the beginning she would try to say her name and call her something not even remotely similar to her name.
She now has other family members doing the same and they won't use her name either, even though they did to begin with.
DH, tells her all the time that she is being silly and to just use her name, she will then just fall out with us.
I know her name is unusual but it is beautiful (in our opinion) am I being unreasonable to tell her she has to use her name?
