How do you say 'I love you my little one' in French?

"J'aime tu, mon petit," is French for "I love you, my little one." It's pronounced "jem too, mon peh-tee."

If you're saying it to a girl, you'd say, "J'aime tu, ma petite," pronounced "jem too, mon peh-teet."

If you're talking to an elder, someone who's not a family member, or more than one person, you'd use vous, the polite form of tu: "J'aime vous, mon petit."

Most French people would say, "Je t'adore."
