Episode 1

It's Billie's birthday and Greg has a rather unusual treat in store for her this year - elsewhere, Arthur acts up at a family photoshoot and there's excitement around the gender reveal of a new arrival. Meanwhile, Margot is on the move and Billie and Greg urgently need to babyproof as it's time for her first pair of shoes, but there's massive cause for concern after Chatty drops a devastating health bombshell.
