I explained to them that I stutter, and will block on a word sometimes. When that happens, please do not finish my sentence or words for me. I also explained that side conversations tend to distract me which can cause me to stutter more, and so side convos needed to be non-existent while I was talking. I didn't say anything about laughing, or snickering, and have yet to have an issue with it. If it does ever happen, I'll focus on respect and consideration. It's my 3rd year teaching, and it's not been a real issue, or roadblock. There was one day where I had to direct the kids to go through the resources with their tables because my fluency was so bad, but it's only happened once. Be upfront, don't act like it's a disability, and don't pay it much mind, or at least act like you don't. Definitely don't let your stutter hold you back from doing what you want. I do have days of poor fluency, and it's easy to blame the stutter, but I gotta keep swimming. It's also a great tool for when a kid says they can't do something, or have a disability of their own, they can relate and see it gets better!
