Ben is still desperately trying to forget that Katy had a one-night stand just before she announced she was pregnant. Nine months later a new baby explodes into their lives creating utter chaos. As a lack of sleep, a lack of trust and a lack ofasex! wreaks havoc upon their lives, it seems like there is no returning to the way they were. That is until Ben comes up with the answer to get them back on track. A role swap! But being a stay-at-home dad isn't as simple as it seems, in fact it's a disaster. Help comes when Ben least expects it and arrives, in the most unlikely form, of the wife of Katy's ex-lover. Should Ben tell Katy about his secret rescuer or is it his turn to keep a secreta? Can any relationship survive NO SEX, endless lies and conversations about nappy rash?
