School's out for the festive season, so the mums (and Kevin) are busy prepping for the ultimate in blended Christmas celebrations. It's a full house at Julia's with an invasion of grandparents demanding endless cups of tea as they play with a VR headset Paul bought 'for the kids'. Julia has invited Kevin along too after learning his alternative was turkey crisps from the hotel vending machine with the other divorced dads.

Kevin excitedly offers to whip up a full-on Persian feast. Liz also turns up when her ex falls asleep on a train following a massive Christmas Eve bender, letting her down on his first ever offer to host. Meanwhile, Amanda is spending Christmas Day with Johnny, the kids and Johnny's new wife Tamara. Which is fine. Really fine. It's fine.

Amanda's PTA charity FUNraiser is doubling up as her birthday celebration meaning everyone is dragged into a big event.

Mixing sponsored cycling with Anne's lethal cocktails, results in a night of high drama and big revelations. Julia is ready to call time on her marriage to Paul and run off with builder Garry; Liz is thrown by the arrival of an unexpected visitor; and Meg rides high on her cancer all clear.

Meanwhile Kevin's attempts to clear the air with Amanda just make everything worse, and a put upon Anne finally loses her rag.

It's time for the year 6 school trip and Julia, Liz and Meg find themselves on the coach journey from hell with humourless school secretary Mrs Lamb and clueless teaching assistant Ms Vaughn.

It all kicks off when a boy banned for bad behaviour is allowed on the coach along with his mother Ashley and Liz decides to play the hero.

Meanwhile, Kevin takes his driving test and Amanda pivots her lifestyle brand Hygge Tygge online. She manages to persuade Kevin to help pack up the shop with unimaginable consequences.

It's Mother's Day in Motherland and Julia is feeling completely ignored, while Meg's family have gone way over the top in reaction to her cancer diagnosis.

Anne is beside herself with excitement at the prospect of a day out with her Mammy, while Liz and Kevin try to avoid Mum stuff altogether with a trip to the countryside that becomes an impromptu driving lesson for Kev.

Meanwhile, Amanda's mother Felicity travels from Cheltenham for a gloriously passive-aggressive celebratory lunch.

The mums (and dad) join the merry-go-round of secondary school open days, as they face the choice of where to send their kids at 11. Julia panics about which catchment area she lives in and even considers a fake religious conversion to beat the system. As Kevin's divorce progresses, Liz helps him navigate the shark-pool of lawyers, and makes a worrying discovery about her own situation along the way. Meanwhile queen bee Amanda struggles with playing second fiddle to Meg's illness.

As a nit pandemic sweeps the school, Julia finds herself accused of triggering a second wave. Ostracised by the other Mums, Julia needs to find a way back into their good books so she throws a nit treatment party that brings everyone's drama (and headlice) into her home.

The party reveals that Anne has some big news, Meg is facing a crisis, and Kevin has committed a terrible crime of passion. As Amanda super spreads the gossip, Liz waits for news about a career move.
