It's Lauren's birthday and she tells her younger sister Millie that all she wants for a present is for their mum and dad to get back together, but it turns out that Sharon has been dating her personal trainer, Mike.

Lauren and Millie try to coax a reluctant Tony back onto the dating scene, but the first date is just like Sharon. Meanwhile, Sharon tries too hard to impress Mike, and gets in a personal trainer to help her get in shape for the 10K run (that she lied about being able to do).

Sharon and Mike leave Craig in charge of the girls when their usual babysitter cancels, and he quickly shows them who's in charge. Sharon and Mike have dinner at a restaurant — but Tony brings his date Amber to the same place.

Tony has a date with Amber, who the girls think is way out of his league – so they decide to give him a makeover. But it turns out that Amber likes him for who he truly is. Meanwhile, Craig makes Sharon's plan to create a new sausage sensation even better.

Amber brings her kids Fran and Jake over to Tony's to meet the girls on Halloween, and things are more frosty than spooky, especially when Jake destroys Millie's costume. Fran covers for Jake, and tells Millie she did it — but will the truth unfold?

Millie has to give up her bedroom when Mike and Craig move in. Lauren goes over to Tony's for peace and quiet – only to find that midwife Amber has brought a patient home with her. The patient ends up having her baby in the flat – which pleases Lauren in that she can finally get an A on her biology homework.

Millie overhears Sharon and Mike discussing holiday in France, and plans an invitation for herself and Lauren. She ends up playing her parents off against each other in the stakes; but ends up with a disappointing result for herself, Lauren and Craig when the French holiday does not turn out as expected.

Lauren's favourite band (The Temper Hearts) are playing a secret gig, so she abandons her previous cinema plans with Millie in favour of seeing them. Lauren infects Amber with the Temper Hearts Fever, and Millie, and Tony, upset because he didn't get a date with Amber, try to stop it.

Lauren's new smartphone is driving everyone mad, but the device goes missing after Mike finally confiscates it. Millie is accused of stealing the phone, and must prove her innocence.

Sharon is buying a cot, researching baby names and calling nurseries. Millie, Lauren and Craig believe she is pregnant — and the truth must be revealed.

Mike successfully applies for a year's contract job in Bermuda – but Millie is less than pleased. As Craig schemes to keep the girls from ruining his dream year in paradise, Millie realises she can't hide her doubts — and announces at the eleventh hour that she doesn't want to go.

It's Millie and Lauren's first Christmas since the separation, and for Millie, it is the chance for a fresh start — for once, a Christmas without family arguments. She persuades everyone to leave their past Christmases behind, and invents new traditions for the family. Some struggle with it, especially Lauren, who wants everything like it was.
