As a mother and Speech Language Pathologist, I recommend to give her some time and don't pressure her to say it correctly. Most children go through a stuttering phase at different points of development. Their vocabulary is increasing, their thought processes are becoming more complex and they just have more to converse about. My 4 year old son has gone through about 4 episodes of stuttering. They have lasted as little as 3 days and as long as 2 weeks. It was heartbreaking as at one point he said, "Mommy, I just can't say it". If the stuttering continues, or changes in nature such as silent blocks (where she can't get anything out), or you see struggle behavior (tightening in her neck, tapping her hand on something, turning her head, etc.) I highly recommend visiting a Speech-language pathologist who can give you more strategies to help with the stuttering behavior. Give her patience and time and let her say it in her own words. Also know that once she is three years old, she is entitled to therapeutic services through the public school system. You would have to contact your local Exceptional Children's Department to have an evaluation. Best of luck!
