We are going through the same thing here with my DS. He's 5. He has a persistent cough. If he gets a virus, he starts to vomit as his lungs produce too much mucous. He has a slight wheeze when he is sick until he gets the antibiotics. He has been sensitive to cooler temperatures since birth. I have also noticed if he has an ice cream or a cold yogurt that increases the chances of him coughing later on.

I have discussed it with my GP several times and they just say 'maybe'. He has a puffer with a spacer and we give it to him when necessary. I'm not sure what to do either!! My DH has asthma though he got it later in life. DS also has a nut allergy and had exczema as a baby.
