The girls spend Christmas Eve and part of Christmas Day at dad's home, but Millie is surprised by her grandparents' arrival.

Millie discovers that Mike has lost his job at the gym, but he is too depressed to tell mum. Millie and Lauren try to find him a new job.

Millie has to choose her school subjects, and her dad has taken a full-time job that really doesn't suit him.

When a new frontman joins Craig's band, Craig is told he needs to buff up and look the part - or he's out.

Millie and Lauren compete to give dad the best Father's Day, like they do every year. But when Lauren raises the stakes by getting a card for Mike, it's game on - who can show they care for their stepdad the most?

Determined to win the school's big Eco Challenge, Millie goes green and insists the whole family make do without the internet for a week. Mike's not hard to persuade, so off goes the wifi! Craig and Lauren are livid, and join forces to out-green Millie until she cracks: no hot water, no lights, no heating. Dad is cynical about Millie's chances of changing the world, and when Fran finds out why, she takes him on a journey into his own past. When Millie's favourite band release their new video exclusively online, she's caught in her own green trap, and Craig and Lauren relish seeing the tables turned.

Mum and Mike plan a half-term caravan holiday, but the kids rebel - they want to spend time away from the grown-ups. So when the holiday is cancelled, they find Mum and Mike getting under their feet. It seems the parental tables have turned - so Millie arranges a 'playdate' for them over at Dad and Amber's. Surprisingly, they get on great and a full-on karaoke party follows. Alone at last, Millie, Lauren and Craig can get on with what they want to. But can they manage as well as they think in a parent-free world - especially when a huge storm is brewing..?

Lauren is completely loved-up and ignoring Millie. Missing her sister's attention, Millie pretends she's had a valentine from a new boyfriend. Eventually she is forced to invite the made-up Grant round to tea the next day. Naturally enough, the entire family want to meet this wonderful-sounding boy. Meanwhile, Craig impresses Fran when he sticks up for Jake - and soon she's got hearts in her eyes too, to Millie and Lauren's horror. Do they need to stage an intervention - or will Craig put her off without their help?

When she realises it's finally time mum and Mike got married, Millie persuades Lauren and Craig they should 'propose' to them. It's a yes - and full steam ahead to the wedding! But the only available slot is just days away, and there's almost no time to iron out the details. Has Millie made the biggest mistake of her life? Even dad and Amber are invited, and dad's going to make a speech (written by Millie, just in to be on the safe side). It looks like they've pulled it out of the bag and romance has won the day - but then Amber goes into labour at precisely the wrong moment.
