As others have said, that is not how language acquisition works. Stuttering is not contagious, not does one learn stuttered speech. Think of it this way: “If you had a limp when walking, would your child learn to walk with a limp? If you child does end up stuttering it is NOT your fault. Stuttering is genetic and sometimes it can be a hit or miss type lottery! I have two children and both a fluent. I have a friend who stutters and their children stutter. If you could does stutter what better household could they be in?
