My daughter is 4 yrs old and has weight 13 kg consistently for past 1. 5 yrs. Also she is frequently ill by day to day cold, fever and vomiting. We have been taking every care regarding hygeine. Also she suffered from chicken pox 20 days back followed by post viral fever. Her cough also is frequent. In past 4 months she has been infected by sometimes bacterial infection, diarrhea, viral fever resulted of lymph nodes at sides of neck, still in small amt visible. Please advice some kind of medicine/immune system strengthening tonic for her.
Thanks for asking. I have gone through your question and I understand your concern. Your daughter who is 4 years old is not doing well since last one and half year. She has having recurrent cold cough, and she is also episode of chickenpox 20 days before, and you are interested some medicine to boost her immune status.  If I was your treating pediatrician I would suggest you multiple vitamin that can contain and vitamin A. In India it is marketed by the name of spy A to Z. If she underwent blood investigation and her hemoglobin was below 11 you can add iron. Hope I answer your question
