My son was just diagnosed with RSV. He's 5m old. He is extremely fussy to the point of being inconsolable most of the time. Appetite has decreased and his sleep is all messed up! With there being no medicine that he can take to help since it's a virus what can I do to help him? Also what do I need to keep an eye out for to know when I need to take him to the hospital? Neither one of my girls ever had this to my knowledge and if they did it wasn't this bad. I'm worn thin on 4hrs of sleep right now.
