Peter and Lois have 2 sons:
Stewie Griffin
Chris Griffin
Stewie Griffin (Seth MacFarlane) may be a baby, but he is as diabolical as the worst villain. He is highly intelligent, but he's still very attached to his teddy bear, Rupert.
He has schemed many times to destroy Lois, but has failed at every attempt. In early seasons, it was insinuated that Stewie is h0mosėxual. In recent seasons, the writers have become more obvious with his sėxual leanings, though the humor is usually couched in Stewie's complete ignorance of his own comments.
Chris Griffin (Seth Green) is Peter and Lois' eldest son. He's not terribly bright, but he is a talented artist ("The Son Also Draws") and rock singer ("Saving Private Brian"). He admires his father and follows blindly into many of Peter's misadventures. Also, he fears the crazy monkey in his closet.
