Greetings from health care magic
This off and on various complain have many reasons. But the 1st thing is as he is only two year of child her immnity is very low to resist different thrush
of infection at some period of time. So there are the symptoms of different ailment. Yes she requires the treatment as per the symptoms. But side by side it is highly essential to enhance her immune power to resist those infection. For it some thing change you have to bring. first give her healthy foods like natural fruits, vegetables, citrous fruits. Avoid all junk, fast, artificial processsing foods. avoid giving chilled , frezed food, ice cream, chocolat. Besides that start a purely constitutional homeopathy
treatment which will help to enhance her own body immune power. So that she will not fall again and again by different health problems.
Hope it will help you.
