The child woke up today with a hoarse voice and a slight fever. He's being fussy. There's no cough. I think he will have a cough soon. What do you usually do in such cases? And how often do you get sick? We last got sick in April with stomatitis, then only yesterday our daughter had diarrhea (intestinal infection) and today... I thought her throat was already used to cold drinks. Yesterday she gave her cold water, but she never got sick from it before. By the way, we have heat.
