Josie and Finn's marriage has been going through a stressful time, although they very much love each other. It doesn't help that their six-year-old son George has ADHD and is extremely difficult at times. They love him dearly, but their lives (particularly Josie's) have been disrupted since his birth, and although Finn wants another baby, Josie isn't sure at all. Then she discovers that she's pregnant, and panic sets in.
