Thanks for writing to us.,
The condition that you are describing is called "Acute Exacerbation" of Chronic Allergic Bronchitis
.This condition of acute exacerbation /acute severe attack is due to sudden exposure to allergens such as House Dust Mite(most of the cases), Pollen Grains,Dust,.The exposure releases a cascade of bio-chemical reactions in the body releasing bronchoconstrictor chemicals from mast cells(histamine
and like). the 02 years old child's bronchi are naturally small and when it constricts with filled up secretions the air passage gets narrowed leading to laboured breathing.The resultant sounds are medically refd to as Rhonchi and Rales.The Condition as "Acute Severe Asthma"(Childhood onset).
The best treatment is to find out the cause.Completely keep the house Dust Free.Nebulise with Broncho dilators and Steroids(Budecortil).Prophylactic Antibiotics.
As the child crosses into boyhood , the airpassages size will increase and the child will definitely overcome the problem as the Bronchoconstriction
will not have marked effect and there will be no precipitation.
The inhalers are better than the Tablets./Syrups and Injections because they act locally and do not produce systemic side effects.
Wishing a speedy recovery.,
