I am 34 years old women. I have delivered twins this year in jan. From childhood. I have been suffering from stammering. I have swallowed my grand father's medicines when I was 10 months old and soon I have started speaking. I stammered. Though my mother also had history of stammering. I just want to know is stammering is genetic or due to medicines I suffered. M having twin boys. I afraid if they catch stammering. I want to cure myself. Since they are small to speak now. Seeking your advice in this. Thank you.
