Emma (Good Luck Charlie)

Emma is a teenage girl that PJ met and developed a crush on in the second episode of the first season, and accidentally switched strollers, as they were identical, and PJ wound up taking home her baby brother and her leaving with Charlie.

Personal life
She meets PJ Duncan in the park, and while talking, they accidentally swap babies. Fortunately, they were able to retrieve them back ("Baby Come Back"). Amy and Bob found out. Bob paid less attention to it

PJ Duncan
PJ has a crush on Emma, a girl he met at the park, who gives him his phone number, indicating that she may like PJ back. Because of this, he accidentally swaps babies with her. Fortunately, he and his siblings were able to retrieve Charlie back.

PJ also got angry at Emma because he thought she gave him the wrong phone number, but Emma explains that he just got it wrong. PJ replies with an "Oh...". PJ asks what Emma is having, and Emma leaves ("Baby Come Back").
