Household illness with new baby

How does everyone handle household illnesses when you have a new baby? I also have a five-year-old who brings home lots of viruses from activities and school. When she gets sick with fever, my husband usually takes care of her… at least until 24 hours after her fever passes… And I isolate with the baby so we can try to prevent our whole family from getting sick. Does anyone else do some variation of this? I just feel bad I’m not the one taking care of my 5 year old but I’m grateful to be able to divide and conquer with my husband.
