We’re you over protective with your new born?

I’m currently getting shit from far away family members because I have planned to not let my new born near anyone who isn’t my immediate family members or my S/O. My baby is due in November and with all COVID going around I want to keep her as safe as I possibly can. I don’t want to come off as rude but I’m so terrified that she will get sick. I’m even being strict with our immediate family I don’t want anyone kissing my new born or grabbing her without washing hands/ face mask. Am I over reacting? I’m a first time mommy and I feel like I’m being such a bitch I feel guilty.
