Hello Sir,
Cough is very common in this month with weather changing and it can be very easily treated with Homoeopathy.
As your wife is 9 months
pregnant, chronic cough is not good for her health as when you cough,your diaphragm is pushed down and it applies pressure on the uterus (your baby's home right now).
Next Steps
Consult a good homoeopathic doctor in your area which gives homoeopathic medicines and no more than one medicine at a time and no patents.
I would advise you to go to Duggal Homoeopathy in Chandigarh and ask for Dr. Monika, and for any help tell her my reference.
