I'm sorry to hear that you're having this problem! I would be interested to know more about exactly what the cats are doing that concerns you, as true "aggressive" behavior or serious fighting would be unusual to see in a kitten this age. Normal play between two cats (including wrestling and biting) is often mistaken for fighting by owners, so I'm wondering if your cat may actually be playing normally with the younger kitten. If this is an aggression problem, this is quite serious at such a young age and would best be handled by a veterinary behaviorist - he/she can evaluate your cat to help determine what is causing the aggressive behavior, and put together a detailed treatment plan to work on the problem. This would likely include some methods to redirect her to some other activity if you see warning signs of an attack such as stalking, growling, etc. as well as possibly medication of some kind to help treat her aggression. Your veterinarian should be able to refer you to a behavior specialist in your area, if you ask.

I don't know how old the kitten is--this matters because young kitten play behavior that seems aggressive is usually intended to be play, whereas an older kitten or cat (say older than 6-8 months of age) starts to have more sincere shows of aggression. It may be that your kitten sees your son as a "toy," and he reacts--runs, squeals, flails, etc and these motions are rewarding and entertaining to your cat. Sometimes teaching kids how to react to animals can be extremely helpful. Here is an excellent article that may help you. https://www.catbehaviorassociates.com/cats-and-children-10-things-every-parent-should-know/ As for the cat, understanding why she's behaving this way will help you put an end to it. See this article: https://www.aspca.org/pet-care/cat-care/common-cat-behavior-issues/aggression-cats I hope thats helpful for you.
