Seek professional advice. There are treatments for preschoolers that are effective. Lookup “The Lidcombe Program”. Some tips: - don’t correct stutters. This is a part of the Lidcombe Program but you need to know what you’re doing. - give your child time to speak. - create a nice speaking environment. This includes: - asking closed questions. Yes, no answers etc. don’t ask “what did you have for lunch”, instead ask “did you have rice for lunch?”. - try to do have 1:1 play time with your child every day for 10-15 mins, where you create a perfect environment for them. Slow speaking, closed questions, let them lead the play. - speak slower around them. - if they stutter, maintain eye contact, get down on their level and wait patiently. Seek advice from a professional though!!!
