Hi Amali Precila, Welcome to Healthcare Magic and thanks for your question. Stammering for temporary periods is not at all uncommon among pre-schoolers. This is because this is a crucial age for speech and language development and many children between the age of 1 1/2 to 2 1/2 years stammer temporarily. This is called developmental stammering. While most stammering is outgrown, rarely some can persist through adulthood. Now, there is no definite way to say if a stammer will become permanent, but there are a few indicators for that: 1) family history of stammering 2) persistent stammering for more than 6 months 3) late-onset of stammering (usually after 3 1/2 years) 4) co-existence of other language and speech deficits 5) boys have a 3 to 4 times higher likelihood than girls Generally, we advice that you don t have to be too concerned if the stammering is mild, if it does not persist for more than 6 months or it does not get worse with time. I think you need not worry too much about Amanda s stammering right now and can just wait & observe. All the best. - Dr. Jonas Sundarakumar Consultant Psychiatrist
