Rant about naming my baby?

Kimberly
So I'm almost 29 weeks pregnant and I've had both gender name picked out before i even conceived, my sister in law who I adore was already 12 weeks pregnant when i found out i was pregnant. She didn't have any names picked out for a while but we told her ours before hand just to let her know, and so months went by and she had her baby December 28th and named her Girl Alexia , but the problem is were having a girl too and naming her Lexie (which we have had the whole time) and so we didn't really care too much that she named her that its just some of my fiances family is like why are u naming her Lexie is so close to her name? Like as if we didn't know that already but my side of the family just loves the name and we cant get it outta our head, anyone have any similar problems with family members naming their child close or anyone bothering them about it? It doesn't frustrate me until someone asks us why were naming Lexie like because we want too? And we had the name first? Idk I'm ranting and I'm in the 3rd trimester and overly emotional and over thinking everything so I'm sorry if this is long just wondering if anyone had any thoughts thanks! ❤
