He wants a jr. But...

Tatyana • Due aug 6th. Patiently awaiting my prince.
Kind of long but please help me before its too late lol. My SO is adamant he has a Jr. This is my first child and his first son. I just hate his middle name so much and his first name is sooo common. I do not want my poor son with hose names . idk what to do?? Ever since we saw his little ding dong at the ultrasound he's been screaming Jr. And he's so proud and he's been telling everyone. Idk how to tell him I don't want my son to have his name without hurting his feelings. Even his mom is all excited. I would feel like I completely had no part in the name if he was to take his name. I'm willing to compromise and have my SO first name as his middle name ? But I can't seem to bring it up. Advice ??
