Low hb and high wbc. Cold and fever.

My baby is 14 month old. His weight is 10 kg. His Hb is 8 And WBC is 15900. He has suffered by  repeated episode of cold and cough. And occasionally fever . His head and palm and feet remain warm 24*7. Apart of this he is still suffering from ear infection. Even his ears are very clear and dry several drops have been used still he feels uncomfortable . in night he keep rubbing and itching his ear canal. And lie on either side of ear on stomach keep turning left to right and so on. No ear pain. But kind of sensation I feel. So his habit affected like bending  his neck to left or right or rub his ear on floor. So please solve two issues How to increase HB level fast and maintain strong immune system. And how to deal with ear no liquid no wax dry ear and clear . I thing something below ear canal. And suggest if any vaccine required for cold and flu bcz he cought very easy cold and fever. Thank you
