Amy used to be on the local news team and was also a poet in her high-school days.
A running gag on the show is that she was involved in virtually every extracurricular activity at Southwest Denver Community College but still earned a nursing degree.
Also, she can be seen as not liking Toby as in the episode "Doppel Date" when she asks Bob if Toby is going to stay at the hotel and he says no and Charlie asks if they can talk about it.
(Eric Allan Kramer) is the father of Teddy, PJ, Gabe, Charlie, and Toby, and husband of Amy.
Toby was born on her birthday; she responded to this by "I like this present." In season three, her personality begins to develop, as she is seen as sneaky and mischievous, such as pretending to like a doll Amy bought for her to like Toby, then throwing it away when she was not looking; and also telling Amy's "friends" what she really thinks of them, causing her to lose them all.
In the middle of the third season, Amy quit her nursing job to be a stay-at-home mother to Charlie and Toby.
In the final episode, Amy is chosen to be the new anchor on "Good Morning, Denver", thanks to Charlie calling in during her on-air audition.
"Gabe" Duncan (Bradley Steven Perry) is the middle Duncan sibling, being both the younger brother of Teddy and PJ and the older brother of Charlie and Toby.
From the beginning Gabe doesn't approve of Charlie's arrival and is the last one of the family to get used to her, but finally he reaches the point of reluctantly assisting in her care and demonstrating some fondness of her.
