Violet Baudelaire was the eldest Baudelaire child. She was 14 years old, right-handed, had a real knack for inventing and building unusual devices. When Violet Baudelaire tied up her hair like that, it was a sure sign the pulleys, levers and gears of her inventive mind were working at top speed.
Klaus Baudelaire was the middle child and only boy. He was a little older than 12 and wore glasses, which made him look intelligent. He was intelligent.
Sunny Baudelaire was an infant, a word which here means “a person of the age at which one mostly speaks in a series of unintelligible shrieks”, so most people had trouble understanding what she was saying. What Sunny lacked in communication skills, however, she made up for with the size and sharpness of her four teeth.
