Welcome to HCM ,
I must tell you that her hb% is alarmingly low & suggests of anemia
a major causing shortness of breath
, anorexia(loss of appetite ) & other symptoms mimicking Bronchitis
Thus , you must consult a pediatrician
for knowing exact cause of HB% Lowering , many a times it is easier to diagnose ,with minor infestation of worm in gut or simple jaundice
So ,i must advise you to consult a gastroenterology department along with pediatrics expert for thorough investigations .
