Is this rude or not

Last year I was pregnant and I ended up having a baby boy. However I had come up with both a boy and girl name and told my brother and sister in law. I still intend on using the name I chose if I have a girl (I plan on having 4-5 kids). My sister in law is now pregnant with a girl and they plan on using the name I’ve always wanted. Is it stupid that I’m mad or is it actually rude of them to do that. I’ve personally loved this name and always wanted a daughter with the name for years.
