It's Millie's 13th birthday - a teenager at last! Both Mum and Dad want to throw a party for her, but Millie can't decide which she'd rather have - Mum and Lauren's teen disco party, or Dad's more old-school cake-and-games version. What kind of teenager does she want to be? And why does she have to decide? The result is two rival parties in different rooms - and Millie realises she's going to have to do something. To make things worse, Craig accidentally creates an 'open' invitation to Millie's party - and only Lauren stands between the front door and a full-on teen invasion. Show less
