3yr old DS is, I think, suffering with hay fever. Runny nose, gunky eyes, coughing overnight. No infection. Our house is surrounded by lots of trees , hedgerows, and rape fields. So I think it might be hayfever.
I've read the piroton box and it says to give 4 to 6 hours apart. Do you give it 3 or 4 times a day as a matter of course? For weeks on end? Or just when it's really bad?
