Hi Expert, My son is 19 months old. He bables , makes sound, shows non verbal communication, social and active. He has yet not started speaking words. During the last routine check up, our pediatrician prescribed Cognium Syrup (5ml twice a day) and said it tried and tested medicine that would help in the development of the baby's verbal skill. Is it safe medicine and are we supposed to give this for baby's verbal language development. Or it is normal to wait for a few months for the baby to speak. Thanks & Regards Swarna
