Hi my daughter is 2.4 years ( 11.5kg) my question is my daughter getting sick again and again like she is catching  every current viral or infection . Last year in  may she was in effect with typhoid fever 105 f. Then this year in January she was affected with viral fever 103 f for 3 days. After that in April she is in effect with stomach flu with low grade fever for 2-3 days. Now in July she is suffering against cold and low grade fever... All fever and infection come suddenly mostly at night. I didn't understand it's normal for kids or there is some kind of issue please share ur opinion .
