Option 1 worries me as it may cause problems for the person who doesn’t share a last name with our child (probably me as DH’s last name is marginally cooler)
I think you’ll find that every single woman who has posted on this topic in the history of MN has eventually chosen her husbands name to be the last because
His is easier to spell
His is more unique
His is more common
His is less common
His is more foreign
His is less foreign
His name works better with this first name he has chosen
He has no siblings
He has many siblings
He has a small family
He has a big family
His name is is own name whereas hers is just her fathers
Her name is weird and embarrassing and she is desperate to change it, even though her father and none of her brothers, uncles and make cousins feel the same way
It would upset his parents if they don’t chose his name and they are lovely people
It wouldn’t upset her parents if they Don’t choose her name because they are lovely people
It Would upset him if he didn’t get his own way As he’s a man
She is used to not getting her own way as she is a woman
He wants them all to have a family name but not enough to actually Change his Own name
Changing names is a lot of hassle for men but not for women
Women are better suited to the tedious admin involved in name changing
But “His is more cool“ is a new one for my list, so thank you.
IMO If you have to choose between which parent’s name, then it’s more practical and fairer to use the name of the person who is the main carer, as they will be with the child most often.
