What do you do when kids make fun of you?

What do you do when kids make fun of you? So I coach a swim team 3 times a week and I have coached them since May of this year so like 6 months so we all know each other already and I used to swim at this club to so everyone knows I stutter. I co-coach with my friend who is the main coach and she does most of the talking but sometimes when I talk to the kids who are like 6,7,8 they tend to laugh and make jokes right in front of me which I know is normal for their age but like what do I do about it? Does it really bring me down no, not that much but I was wondering what would y’all do?
