My DS is two and a half and he seems to have coughs all the time. In the last 4 months he must have had about 5 bad coughs. His pediatrician has said that it is normal at this age. A couple of times it has developed into bronchitis. I am sick of constantly having to give him cough medicine and being awake all night listening to his coughing! He doensn´t seem to be all that bothered by it but it sounds awful to me! Is this a common thing for toddlers to go through??
