Kate Read

Kate Read is the one-year-old infant daughter of David and Jane Read and the younger sister of Arthur and D.W., who lives in Elwood City.

Early life
Kate was first seen as a newborn in "Arthur's Baby" and "D.W.'s Baby".

Season 1
On her first birthday, Kate puts her face in her birthday cake.

Growing Up and Future Life
First revealed in "Paradise Lost", Kate is getting older and becoming less able to talk to Pal and more able to talk to other humans. "Mei Lin Takes a Stand" also shows she is able to walk short distances.

Physical appearance
Kate is an aardvark like her parents and siblings. She wears a pink shirt, green pajama pants, white disposable diapers, and a bow with a hairclip on her hair. Her swimwear are swim diapers that are about the same color as regular ones, a red bathing shirt, and a white bathing cap with red polka dots. When she was a newborn, she was wearing pink footsie pajamas with green accents. She also had a pacifier in her mouth; but since she became a year old, she has rarely had one. An early Kate can be seen in "Arthur's Baby" and "D.W.'s Baby".

Personality
Kate is able to communicate with Pal, Mei Lin, and other animals or babies. Anybody who is older than her dismisses it as "baby talk" gibberish, and she and the animals interpret grownups' talk likewise. She enjoys playing in her sandbox and shows remarkable intelligence for her age, despite not being able to communicate with people older than herself. But in one episode she couldn't hear Pal correctly at times. Despite being a year old, she rarely stands up. On certain occasions, she is prone to crying. At one point, she threw a tantrum over wanting a balloon, and Pal ran off and brought her back one in order to cheer her up.

Trivia

 * She is modeled after Marc Brown's youngest daughter, Eliza.
 * A running gag is her first word, ranging from "bloog-agwa" to "Brain" or "D.W." This causes many continuity errors within the series.
 * She can talk, but only to animals and other babies (similar to Rugrats). She also talks to the viewers when she's featured in an episode's intro.
 * She understands what Pal is saying.
 * She can say "D.W." by copying D.W.'s lip movements, but she says "D Double woo".
 * On her Trading Card, her age is listed as "Cute", even though she is one year old.
 * In material related to the series, she is commonly listed as "Baby Kate."
