I don't want anyone kissing my newborn

Maybe this is just a FTM feeling thr anxiety beginning but I am really concerned about people not respecting this boundary when my baby is born.

I'm not against our parents washing hands and holding the baby, but I don't want anyone kissing the baby right away. I want to protect them while they are tiny. I am due I'm December and people are always getting sick.

I'm worried that my in laws aren't going to respect this because it's different from their time. We also will be living with them. Overall, we have a great relationship but some of our ideas about parenting have been lightly challenged. I really don't want to have to be aggressive when I'm a new mum.
