On 25 May 2004 Barker announced that she was pregnant with her first child, by husband Michael Todd. A boy, Dexter Jack Barker Todd, was born on Saturday 4 December 2004 and featured on the show many times, including at just 13 days old, on his first birthday and on Barker's leaving date. While Barker was pregnant, scan images were also shown. She became the first presenter to rejoin "Blue Peter" after having a baby, but on 23 January 2006 she told viewers that she would be leaving the programme at Easter and moving away from London so she could spend more time with Dexter and the rest of her family. She was replaced by Zöe Salmon, who originally took Liz's place in December 2004 when she had her baby.
