Please look up Camp SAY. Great resource for kids and parents alike. I am 21F stuttered since I was 2 and attended Camp SAY for six years. It provided me with massive self worth and acceptance with my stutter. It is for kids 8-18 so your littles are a bit young for it yet, but it has great resources for parents of kids who stutter. Also, the National Stuttering Association (NSA) also has good resources and information for parents.
