My husband & i have decided that he will choose the name for our baby if its a boy, and i will choose the name if it is a girl. we are both 23 and this is our first child together, we are super excited. well we told the family about that and his mother thought it was adorable we were doing that, we went home later that night and we got a huge text from his sister ( she is 25 ) completely going off because we arent allowing anyone else having a decision in the name picking of OUR child? she said she wasn't coming to the shower, shes done with us and that we are selfish?? His mom and his other sister are completely on our side and said that she has no right to be mad about this. but she is in the wrong, right? like she shouldn't be mad because we aren't letting others ( his or my family ) have a decision in the name of OUR child.
