Hi all. My dd started nursery in September and about a week in developed what we thought was a cold, but this has lingered since, at times worse, but always there. We''ve been to the GO a number of times, she had an antibiotic before Christmas, which worked for about 2 days, then back to the same again. I started her on zirtek on whim a few days ago and that has made some difference but is not a long term solution. anyone like to hazard a guess? asthma? allergies?
