My 3.5 year baby is having cough from past 1 month no syrups are working what to do

A. Okay try these two things first of all start giving ginger juice mixed with honey with a pinch of black pepper and Tulsi into that three times in the day no water for at least half an hour on top of that second I’m going to recommend you to give pinch of turmeric and black pepper in the mail that you give to the child and lastly you can check with your doctor if you can nebula the child because that is meant to help in clearing the congestion and chest and throat you can usually use water and warm water but for medication you have to cross check with your doctor
