Kissing on baby

I told my mom that when baby comes I don’t want anybody kissing her because I don’t want to risk getting her sick. I’m due in February and I just don’t think it’s worth risking it to let people kiss her. Needless to say my mother freaked out and is totally offended I don’t want ‘even her’ kissing her granddaughter. My question is, am I just being crazy overprotective because I’m a FTM? I didn’t think not kissing baby was a crazy request, but now I’m not so sure
