Reason to be upset.?

Heather

So I am a ftm 23 weeks pregnant with a baby boy. My spouse and I finally came up with a name we kind of agree on. I was excited to tell my mom on what name we were thinking of naming our son, which was, Carter. She immediately begin to laugh and tell me how ugly the name is and if we name our baby that a she will call him "ca ca" because she hates the name. I'm hormonal of course and could possibily be slight over dramatic about being upset about this. Thoughts.?
