hello! I'm a mom and a speech-language pathologist. How old is your son? Stuttering can be normal right around 2-4 year age range- when kids are developing higher language skills such as putting sentences together- and their mouth is trying to keep up with their thoughts. If this is the case- I would let him work through it! I would suggest NOT interrupting him. Give him your attention and eye contact- and some patience to let him get through his communication. Then, when he is done - you can respond positively and repeat his message back to him to help model slow and smooth speech back to him. Letting him work through it and not interrupting him will allow him to learn how to become more fluent. Also- interrupting can actually make him more self conscious about speaking- increasing his stuttering.
If you feel like this is not just part of normal development- then having a speech therapist do an evaluation may be worth it. If he is older than three- you can call your local school district. A speech pathologist will be able to tell you if this is just what we consider developmentally normal- or if it is a true stuttering difficulty- it all depends on what the stuttering looks like, his age, the amount of stuttering, and other factors.
good luck!
