Freaking out!!

We had a huge snow storm last night and my husband was stuck at work. My friend came over with her 5 year old (they’re completely quarantined, he’s immunocompromised) they stayed the night so I wasn’t alone but before we went to bed we noticed that her son has a cold sore! He didn’t touch my baby, kiss him or anything but he definitely touched all of his stuff around the house. I gave baby a bath and have been cleaning and sterilizing like crazy. The baby hasn’t used anything since because I’m freaking out. I know it’s just a waiting game but do you moms think my son will be ok?! 🥺
