Hi there! I'm a person who stutters (probably a 7/10) who is currently studying to become a preschool teacher -- needless to say, I'm around children a lot and need to explain things to them quite a bit! Answers to adults are kind of the same thing. What you can say depends on your comfort level and the time you have to devote to an explanation. If you have time and you're comfortable, this is a great time to advocate for yourself. Don't underestimate the intelligence of the kids around you -- kids as young as 5 have been able to understand when I tell them, "I'm a person who stutters. My words get stuck sometimes. I can't control it, that's just how I am!" Of course, this might lead to more questions, which is why I mention the time constraint. I most often get "is it contagious?" and the (very sweet) "does it hurt?" The best is when it naturally leads to a dialogue about people being different, everyone is different, etc. You just turned it into a learning moment! If you don't have the time or aren't comfortable, a solid "that's just how I speak" normally solves the issue for older kids and most adults -- younger ones might press because they're genuinely curious. I also definitely wouldn't be offended by kids laughing a little. They're probably confused and laughter is just a natural reaction, nothing malicious about it!
