Babyboy name, family issues.

So me and my SO have the name "Draco Lee Gray Taylor" picked out for our son due in February. The middle names are the same as his fathers, my SO. My mom keeps wanting me to change the name cause she doesn't like it. And my entire family is here, on Christmas, telling me he'll get made fun of and i need to change the name. I love the name and so does my SO. I have no clue what to do. I'm so upset. /:
