Amy Duncan is the wife of Bob Duncan and mother of PJ, Teddy, Gabe, Charlie, and Toby. She's a nurse and went back to work after Charlie was born, although at one point she was nervous about leaving Charlie alone with the rest of the family ("Study Date"). She is just like any other mother in the world. She loves and cares about her family, and entrusts them with their baby, Charlie. But at times she is shown to be quite self-centered. She can also try to be the star of the family most of the time. It is also shown to overwork, which causes her to talk baby-like even when Charlie's not around. Because of this, Teddy tells her that they need a break from Charlie, and that they should go on a date. Amy takes Teddy's advice and goes to a Mexican restaurant along with Bob. ("Baby Come Back"). Amy hires a pretend family in a show in her work to beat her work mate Fran which shows that Amy Duncan is embarrassed by her family and their lack of talent ("The Singin' Dancin' Duncans"). Amy is a very kind woman, but is very hard to live with. Amy is occasionally shown to be a bit of an airhead, but most of the time she is very smart and can be quite sarcastic. She is also highly competitive, even over trivial things and less special opportunities, such as being on TV or singing in front of a group ("Kwikki Chick", "Charlie Goes Viral", "Charlie Shakes It Up!"). She is also often shown to be strict in several episodes. Amy loves the camera and the stage and often goes crazy trying to be in anything that has to do with acting or being in front of a camera. She also seems to have a bit of a temper.
Amy used to be a mascot for South High, called Whammy. She dislikes the North High School mascot, a barbarian who always slams her down with his fake axe ("Double Whammy").
She goes back to work after Charlie is born, entrusting her kids to take care of Charlie. But Bob Duncan falls down the stairs and hurts himself, so PJ has to drive him to the hospital and Teddy has to take care of the baby. In the hospital, PJ pretends to be a doctor so as not to be identified, but in the end his mom finds out. She says she can't handle it anymore, but Bob tells her that everything's gonna be okay ("Study Date").
Teddy tells her parents that they needed a break from baby Charlie, and that they should go out on a date. But then PJ takes Charlie to the park and accidentally swaps strollers with a girl named Emma, and brings home the wrong baby. They do everything they can to retrieve the baby, but in the end, they are caught by their parents and get grounded ("Baby Come Back")
Amy suddenly becomes textmates with Ivy, which makes Teddy jealous ("The Curious Case of Mr. Dabney"). Amy and Bob's anniversary is coming and Teddy wants to give them the best day ever ("Blankie Go Bye-Bye") .
It shown that she and Bob are different from regular parents since they punish Teddy and P.J. by dancing awkwardly ("Duncan vs. Duncan"). It turns out that she and Bob weren't legally married but they remarried ("Snow Show, Part One", "Snow Show, Part Two").
She dated Bob Diddlebock before Bob. Diddlebock introduced her to Bob. She still has poems from him. It turns out they are the only boyfriends she had in high school. ("Girl Bites Dog"), ("Ditch Day"). She also received a sports car from him.
In Good Luck Charlie, It's Christmas!, Amy revealed she was pregnant with her fifth child, a prospect dreaded and a running gag in the series thus far. The pregnancy carried over into the third season where Amy was shown to be in her third-trimester. Later in the season, there was an hour-long birth episode. She and Bob never planned on having another child, but for some reason, they did, after saying a thousand times that they would not have another baby and would stop with four.
Amy and Bob Duncan are a married couple. They love each other just as any other couple does. Amy also trusts Bob in taking care of the baby, Charlie, when she is away or goes to the hospital ("Study Date"). Amy states that, since she and Bob sometimes lie to each other, she thinks they had a good marriage lying. Although, Bob usually gets jealous when there is a mention of Bob Diddlebock. ("Charlie Goes Viral").
Amy has a great bond with her youngest daughter. Charlie loves her mom like any other kid does, but Charlie already knows her mom is a little bit of a showoff and wants to be a star, but they love each other very much. Charlie is most like her mom because she also has a very diva like attitude. Charlie is very independent, which Amy hates, but they always somehow work.
Amy has a pretty good relationship with her daughter Teddy, as she is probably the closest kid to her. Amy and Teddy have a lot of fights but they always get through them, and even though Amy gets on Teddy's nerves sometimes, she always loves her mom. Teddy and Amy always get along well with each other, and Amy cares and loves for Teddy. If any boy were to break Teddy's heart, she will break them.
Gabe and Amy have a weird relationship, Gabe is one of the older kids but he is still treated like a middle child. Amy tends to forget about him a lot, but she remembers him the most out of everyone. Gabe also gets annoyed with his mom, but even though he does not show it, he loves her and she does not show it often either, but she loves him just as much as any of her kids. Gabe and Amy have a better relationship in season 4 when he is older.
PJ and his mom have a great relationship, being that he is the oldest and he is "Her Little Boy". PJ does get mad at his mom somtimes but they love each other just the same. PJ and Amy have the best relationship, just not as close as Teddy and Amy's.
Toby is a baby boy and is only 1 year old, so he does not know much. Amy is a very good mom to him even though he can't talk. He loves his mom and she really loves him. Toby and Amy are not as close as Charlie and her were when she was his age.
Jamie is Amy's younger sister. Jamie and Amy's relationship was a bit rocky. Back in high school, Amy stole Bob Diddlebock from jamie, leaving Jamie filled with bitterness and betrayal. So in payback, she did not go to Amy and Bob Duncan 's wedding, hurting Amy's feelings. But in Sister, Sister, they made up. And as a surprise, Amy contacted Bob Diddlebock and told him about her as a surprise.
