Respected Sir, hi I evaluated your query thoroughly.
It`s your child`s immune system weakness that leads to recurrent
cough.
Follow certain steps at home for long term benifits :
* Must thing to do on daily regular basis is Deep breathing Exercises along
with
YOGA 30 min. a day.
* Must walk for 20-30 min. in fresh air for better oxygenation.
* Avoid his exposure to excess
cold / atmosphere containing pollens.
* Give him more nutritious food containing
proteins, vitamins and iron.
* Maintain his hydration level.
* Maintain high level of
oral hygiene.
* Salt water / Peppermint gargles daily 2-3 times a day.
* Intake of Tulsi and Turmeric in desired forms helps great.
* Avoid him giving excess sweets, oily , spicy , chilled water , cold drinks,
dairy products making him prone to susceptible infections.
* Make him undergo his routine immunisation as per schedule.
* Notice if after particular matter he has coughing means to rule out
allergy point of view.
* Can give him decongestants and antibiotics syrups as per guidelines by
Pediatrician.
