Question: who played the middle sister on full house?
Answer: Jodie Sweetin

Stephanie Judith Tanner ( portrayed by Jodie Sweetin ) is the witty , sarcastic middle child of Danny and Pam , the younger sister of D.J. , and the older sister of Michelle . Her mother died when she was five years old . Her catchphrases during the early seasons of the series include '' how rude ! , '' '' well , pin a rose on your nose ! '' and '' hot dog '' . She eventually evolved into something of a tomboy in seasons four and five . Stephanie has a habit of spying on D.J. 's life by reading her diary and eavesdropping on her telephone calls ( having been caught in the act several times ) , and is generally the most athletic and nosiest of the Tanner girls . Her best friends in school are Gia Mahan and Mickey , whom she meets in season seven ( the former is the only one who appears through to season eight ) . Of the three sisters , Stephanie has dealt with the toughest issues , such as peer pressure into smoking ( in season seven 's '' Fast Friends '' ) , '' make - out '' parties ( in season eight 's '' Making Out is Hard to Do '' ) , joyriding ( in season eight 's '' Stephanie 's Wild Ride '' ) , and uncovering a classmate 's child abuse ( in season six 's '' Silence is Not Golden '' ) , as well as the death of her mother when she was only five . In her early years , she is very sentimental about Mr. Bear , a stuffed animal that her mother gave to her after Michelle was born ( this was the focal point of the season two episode '' Goodbye Mr. Bear '' ) . She and Jesse are the most abrasive when it comes to how they feel about Kimmy Gibbler .
