Hi Kookie. My ds7 has asthma. He started with the night time cough, but i don't recall the runny nose...
When he was at playschhol (2.5-3 ish) I reemember he never had the energy to walk there and back. At nursery he would cough at playtime, and gasp for breathe, and then had an 'attack' on hol This is when the doc diagnosed asthma.
He had the brown inhaler in the morn, and he was alot better, so attacks, and i asked if he could come off meds, but then it all revved up, he was tired, and out of breath so easily. he would be triggered by pollen a lot. But he doesn't really have a wheeze ever, its the shortness of breath, and working hard to breath, and the tiredness.
The blue will relieve for 2 hours, and this does make a difference straight away. But if he is having a bad spell he needs a good few puffs. He uses the spacer. It helped him to see an older boy use one.
he is ok at the mo because he has started taking a chewy pill every day, and three months in I am seeing a benefit to him with his energy and stamina.
Hope this helps, so don't worry there is no wheeze. It could be asthma with a cold? or hay fever?
