My son is just over 2 years old now. For the last 2 months he has had a cough. Every single day at least 3 times during the day/night sometimes a lot more and sometimes a lot worse. To the point the he will cough and vomit. Doctor has said it is allergies so he has been on allergy meds for the last 4 weeks. With little to no improvement. Today, he is running a very low fever (warm to the touch but we can't get a good reading on a thermometer). He's definitely off but still playing around and has lots of energy. It's probably just something going around but I don't know how much to worry or think. We will go to the doctor tomorrow.
