I remember when I was pregnant with DS most of our friends knew the name we'd chosen. A girlfriend of one of those friends said "I just hate the name XXXX, that's a name for a dog!".
Well, everyone that knew that we'd chosen to use that name looked at me straight away. I just raised an eyebrow and changed the subject. Afterwards the friend apologised to me but I didn't really take offence. She didn't know what we'd chosen. And she probably felt like a right prat when her boyfriend told her later on that it was the name we'd picked lmao.
I don't understand why it's ok to insult someone's choices before the baby is born. I mean, it's still the baby's name. It's just that the baby isn't out yet. Do they really think that them airing their opinion is going to make you change your mind and pick a name that THEY think is more suitable?
