Hi! My brother is visiting my 8 week old baby and he has a pretty bad dry cough. He isn’t holding my baby but will get close to him (within two or three feet). His fiancé is also here but they are sleeping in our guest bedroom. I wiped down any shared surface at night, am sterilizing all of baby’s binkys, and try my best to make sure his fiancé washes her hands prior to holding baby. What else can I do? He doesn’t get his shots until Tuesday and I’m worried he will get sick.
