Hello Doctor, While my baby drink water he gets cough from initial drinking stage ( 6 months old ) to until now ( 8 months old ). From which ever he drinks either from open glass / bowl - he gets cough and sometimes he vomits. While drinking breastmilk / semi liquid/ puree’s / Ragi malt he don't cough. Does it causes any health issues if he coughs everytime he drinks water? Should I give him water by sipper bottles? Or please suggest any other format or bottles . Please suggest. Thank you.
