Baby name 😩🤔

Kristianna
Is it bad I want to change my sons name? He's being named after his dad. W a Jr at the end.. i agreed awhile ago now I know what I'm having I don't think it's fair cause my boyfriend got is the gender he wanted & now he gets the name lol. This is my first kid & I wanna be able to name him. Am I being selfish? I keep asking him but he says no.Â
