Kissing baby question

Was there a certain age you felt okay or were less strict about people kissing your baby? And by people I mean close family.

We were really strict when my daughter was first born that no one was allowed to kiss her outside of me and her dad and it was like after she got a little bigger, ppl just started doing it all the time and no one ever asked if it was okay now.

My daughter just turned 7 months old for reference here. It’s really just my mom, grandparents, and my father in law. But like why do other people have to have there face so close to other ppls babies anyways😕

My parents had a cookout tonight for Fathers Day and it was like I cringed inside every time someone kissed her & my husband said the same thing when we left. So idk if most ppl think it’s okay at this age or we still shouldn’t be doing it.
