Kinda freaking out

FTM! So my husband came home yesterday from work saying he had a cough so he stayed away from baby (3 weeks old). Went to work today and texts me and says he feels terrible he thinks he has a cold. Asks me what we should do so we don’t get baby sick. I disinfected everything (sprayed couch with white vinegar because I didn’t have anything else to spray for the couch. Husband is home now and sleeping on the couch. We have a super small house so there’s not really anyways to separate him from us. We’ve been washing our hands a lot, I’ve been disinfecting things and he’s not coming near baby and making sure to cough in his elbow. Im just so afraid baby is going to get sick. Idk what to do to keep him safe other than going to my grandparents with him until my husband gets better?
