Good day My husband and my father got sick with a cold, temperature under 39, dry cough, throat. I and the little one are all good for now, but there's fear that we might get sick too ? How can I protect myself and her from this ? We already have regression in sleep and soon a jump at the 4th month, not enough and a cold. My husband sleeps separately from us, I only cross paths with him.
