I am 18M,I don't have a kid but i struggle with kids like ,i could not able to say them to stop doing or deny them for something, i feel insecure that they will notice my blocks or that they will not able to understand me It add extra pressure to not Stutter while talking to them because still i feel awkward about my Stuttereing and atleast don't want kids to question my way of my speaking. Coming back to you ,it may sound cliche but it not like you could escape from your kid forever without him noticing your stuttering, handle the situation without stigmatizing or sympathizing it ,like Stuttereing fall under common speech disorder but people are not properly educated about it. LIKE people who stutter will not have a hard time if people around them are educated and cooperate a little.
