I live with my boyfriend and his family. For the last week his sister and her son have been sick and coming over. I have a 3 week old baby. Me and my boyfriend asked her nicely not to come over and leave her sick son with her mom to watch at night so my baby girl dont get sick. His sister did not listen and now my baby is running a temp of 99.5 and not feeling good. Is there anything i can do to help her get better before her dr says take her to the hospital?
