Would you get annoyed if your friend took your baby name but you never mind giving it on Y/A?

lol. I am pretty funny with baby names. Don't care if it's childish Its my baby name & if my friend called her daughter Isobel i would be annoyed & would have no problem telling her so either lol. Not being horrible but i just feel like that. My cuz has a son called hayden. I love that name & if i had a boy i would want to call him that. i never would though as its her baby name. I come across questions of what to call babies in this section & i never mind suggestion Isobel. & would never mind if they took me up on it either. I guess its because i don't know them even though i talk to a few mums off Y/A. Isn't it funny how we get protective over our baby names lol. Well i do anyway lol.
