A kiddo is a child or young person.
When people use the word "kiddo," they often do it with affection and warmth. Imagine someone saying to their friend's little boy, "Hey, kiddo! Be careful on the stairs!" The tone is usually friendly and informal, like talking to a close family member. You might hear this kind of language in everyday conversations between friends or from parents to their kids. It's also common for older people to use "kiddo" when they're around younger people - think grandparents with young grandkids at the park. Using "kiddo" is like putting your arm around someone and saying, "I'm here for you."
A close friend; especially used as a form of address.
Example: Okay, kiddo, I gotta run.
