I'm really tired of my fiance's cousin always telling me I'm having a girl just cause her 1 year old son always smiling at me. She believe in that "if a boy baby like you then you're having a girl and if a girl baby like you you're having a boy" type shit. I'm having a boy you can see his wacker clear as day on the ultrasound pic. Nah chick your son just gay.
