Wyatt Matthew Halliwell: Wes Ramsey, Jason & Kristopher Simmons - Wyatt, the first child of Piper and Leo, was born to a prophecy that he is the 'twice-blessed son'. Born February 2, 2003, the day of the Wiccan Festival of Lights, he is gifted with much magical power, including being the heir to Excalibur. In an alternate future, Wyatt was kidnapped by the corrupted elder Gideon, and was, subsequently, raised evil. During his adult life he murdered his surviving aunt (Phoebe Halliwell - Paige Matthews had already been killed by the Titans, and the Power of Three was broken) and may have even been responsible for the death of his own parents. He later took over the manor, spread evil through it and tried to murder his brother, Christopher Halliwell, and killed Chris' fianceé, Bianca. Luckily, Chris was able to travel back in time, to before Wyatt's kidnapping, and managed to keep Wyatt pure and innocent. Leo Wyatt, their father, killed Gideon, and Wyatt grew to become a gentle and kind whitelighter-witch, who sacrifices his time in order to vanquish demons and warlocks and save innocents. 'Wyatt' was named after Leo Wyatt and 'Matthews' after Paige, who risked their lives to protect Wyatt.

Christopher Perry Halliwell: Drew Fuller - Chris was the second son of Piper Halliwell and Leo Wyatt. During the time when Piper and Leo separated (when Leo was promoted to becoming an elder) the couple accidentally traveled to the ghostly plane. It was here that, after discussing their true feelings for one another, they conceived Chris. Unfortunately, in an alternate future Chris was raised by his grandfather, Victor Bennett (who later developed a smoking-related illness that may have killed him), after his mother, Piper Halliwell, died when he was 14. Furthermore, Chris had to deal with the fact that his elder brother, Wyatt, had become evil and was responsible for the death of Chris' fianceé, Bianca, and his aunt Phoebe Halliwell. Fortunately, Chris traveled back in time, to before Wyatt turned evil and managed to save his family. He is kind, humorous (although somewhat neurotic; he notes that Wyatt's multitude of powers has left him with an "inferiority complex"), and believes that family should always come first. Chris was named after Leo's father, Christopher, but his middle name is unknown of it's origin.

Melinda Halliwell: After the births of Wyatt and Chris, Piper and Leo had a third child, and their first daughter. She was shown only in a short scene, being sent off to school with Wyatt and Chris, in one of the flash-forward sequences at the very end of "Forever Charmed". The name "Melinda" appeared in one of the episode's casting scripts, but the name was not mentioned explicitly in the final episode. Other than the fact that she exists, there is as little information about her as the eventual children of Phoebe and Paige.
