Hello Doctor, While my baby drink water he gets cough from initial stage ( 6 month old ) to until now ( 8 month old ) . From which ever he drinks either from open glass or small bowl, he gets cough and sometimes he vomits. While drinking breastmilk / semi liquid / Puree’s / ragi or rice 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.
