As such wheezing is a classical sign of asthmatic bronchitis.
Probably this can also be allergic and triggering factor can be changing season,cough,cold etc
Usually broncho-dilators and anti allergic medications are prescribed.
I would suggest a clinical examination by a doctor in first place to confirm the sign and symptoms you are describing.
Persistent wheezing can be a dangerous sign and can be associated with severe asthma and can cause respiratory distress.
Wheezing is like whistling sound while breathing and can also be felt with a stethoscope as well while chest auscultation.
Sometimes,symptoms can be related to cardiac asthma.
So further EKG must be done in her case.
Having said this,if possible visit ER.
Hope this helps.
