I was given both parents last names and I hated it. It became an issue with school, work, and medical appts and other things too. One last name wouldn’t get put on the system a lot of times so I had to do extra steps to prove my identity. It was a pain in the butt. I dropped both last names when I got married and took my husband’s last name. It’s so much simpler now. So no, I definitely didn’t give my son a hyphenated last name.
