AM I CRAZY?!

I have a currently 6 month old. Since he was born I'm very hessitant and "over protective" on people kissing my son. They say I'm exaggerating and that nothing will happen and that It should be bc they're family. But i feel like my son has no choice but to trust me to care, love, and protect him under any circumstances. If you carry my baby and he seems uncomfortable, starts crying, or simply doesn't want to be with you. I WILL TAKE HIM BACK.

You got the flu shot? That's fine, but dont kiss him. I think it's simply and I wish everyone should respect that.

Am I wrong?
