thanks for asking i gone through your question, you are very much upset with your child health. as per your question. your 7 month old child is having respiratory symptoms since last 2 months(i not able to get what symptom she having cough, difficulty respiration, nasal block, fever ????) your doctor give her inhalers. but she not improved. and your worried that your homeopath told you that she developed fungal infection in chest. in my view you have been treated by trained pediatrician .all prolonged symptoms can be caused by asthma. As he advised inhaler pumps. these pump take about 2 weeks for their full effect. so in my view we should give time to get full effect of inhaler pump therapy.if i was your treating pediatrician i would give you simultaneous nebulization therapy which is fast active and give relief till the full effect of inhaler therapy occur. The fungal infection in chest occur in child whose immune system is sick. and is has severe breathing difficulty. and i was picked by your pediatrician .so in my view not to worry with your feeling of fungal infection in chest. for iron deficiency , was your kid underwent hemoglobin estimation. talk with your doctor for iron supplement drop if hemoglobin is low. hope i able to solve your query have healthy family life
