I took my son to the dr on Thursday because hes had a cough for a couple days that's just getting worse and he hasn't been eating as much. They did an RSV test and it came back negative, so they sent me home without any further instructions. Just to keep doing what I was already doing. He has diarrhea now and still isn't eating all that much. Looking for any advice from other parents who have dealt with this. Should I call the dr back? Im just not sure because they kind of shrugged their shoulders and said I don't know. If they're not worried should I try not to worry and just wait for it to pass? Also no fever has developed
