It is more than likely that your daughter does not get bouts of bronchiolitis, but has episodes of asthma triggered by viral infections. In children where the trigger for the attack is a virus, the summers are usually fine and the fall and winters are the problem.
Yes, there is a lot you can do to prevent these attacks instead of simply treating them and worrying if she is going to get pneumonia. I would talk to your daughter
my daughter also suffers from repeated bouts of bronchitis in the winter, although she does sometimes have bronchitis in the summer. The bronchitis agravates her asthma. She also uses a nebulizer for these times but also takes daily meds. for preventative. Right now she is on singular (which helps with her allergies as well) and foradil, and pulmicort inhaler. My daughter is 14 years old and was diagnoise when she was 2. You might want to take your daughter to a pulmonary Doc. Because she is so young they might subscribe different preventatives. Over the years they have change my daughters asthma meds and i don't remember what she was on at your daughters age. I do know that the pulmonary doctor has been more agressive and helped my daughter more than her family doctor. Good luck, I hope it works out for you and your daughter
Go see a pulmonologist,don't take no for a answer your daughter could have a immune disorder or some problem that is masked short term by antibiotics only to repeat again. Run every test they can think of, if they can't figure it out move on to the next hospital. It is frustrating and time consuming but way to important not to.
this is a good website for asthma http://www.njc.org/ when you get to their home page type in interactive asthma diary. you'll come to a page that has an option to keep a daily diary of symptoms, peak flow readings,etc. record your information every day and print it and bring it to the doctors when you go. it's great.
