Dd2 got the flu first. Then dh. Now ds. I'm terrified that our 4wk old will get it so no one has come into contact with her for days. How long do we need to avoid contact? Dd2 started symptoms 4 days ago. Dh 3 days ago. Ds just got sick yesterday. Dd2 and dh feel better. Seems like body aches and fever, but it's gone now. I'm just afraid of leaving the house by myself (grocery run) and having dh care for baby. Is he okay to care for her? Or best to avoid still?
