I think you are pointing it out 100% as his doc used to say same things that its of mild nature and even there are no single asthma like attack in months while asthmatic patients normally having 1-2 attacks in a month are also considered not dangerous. He also told that it will almost be gone by the age of 13-14 as his lungs develop more and would be strong enough to withstand environmental hazards.
As previously mentioned I went to Lahore Chest Clinic Iqbal town but got bad impression by the chest specialist /pulmonologist as he was just dragging pen over the paper to prescribe medicines and inhaler and pretending as it is very big issue and only inhaler use for the whole life is must. He won't budge even after I asking many questions about what it really is and how to understand symptoms and take necessary action in case of emergency.
However Dr. Waqas Sheikh (my son's only physician since 3-4 years) explained everything really well and educated me what to do in any situation. He never used to give extra medication and if i insisted then he would say its not needed.
There are very few people like him and you guys who really want to help others and not just rip off. Salute you guys.
