Dirty Hands

Ok so I know some of you are gonna think I'm being ridiculous but I am OCD and need to talk about this. So like I mentioned I am OCD and a germaphobe so clearly I'm going to be overly worried about germs with my newborn.

I'm worried about those first 8 weeks with germs. I wash my hands always before handling my baby and when people come by I ask them to wash their hands. Well my baby is only a month old. Well today real quick my brother stopped by this am to drop something off. I answered the door holding my baby and from reaction he touched her hand and said hi to her. He didn't realize but I immediately get upset. I didn't say anything but I quickly went inside and was gonna wash her hands but she stuck them in her mouth before I could. so basically he touched her hands with dirty hands and she stuck them in her mouth. He had keys in his hands too. I still went in and washed her hands and changed her onesie.

I am so beyond upset and worried she's going to get sick or contract something (not to be gross but he also doesn't always wash his hands after using the restroom so who knows if he did before stopping over). Can someone please tell me if I should be worried or is this my disorder pushing me over the edge. I'm seriously having a panic attack over this. I am so beyond worried.
