Beyond the Nuclear: The Rise of Shared Homes and Sisterhoods in Modern Parenting
Lauretta Gavin often hears a surprising sentiment from her mum friends: “I want to get divorced so we can live like you…” This sentiment stems from her rather unique living arrangement in the UK, where she, a single mum to 16-year-old Florence, shares her home with her sister, Sharon, and Sharon’s 13-year-old son, Carter. For the past 12 years, these sisters have not only cohabited but have also embraced co-parenting, creating a thriving family unit.
From Necessity to a Flourishing Family
What began as a practical solution born out of necessity has blossomed into a deeply beneficial arrangement. Sharon, a new mother at the time, was navigating a divorce and battling an autoimmune disease. “I was really poorly – I couldn’t cope on my own,” she recalls. Lauretta explains the initial move was purely out of concern: “She needed somewhere to live, she was very unwell and she had a small baby; she moved in with me so that I could help her and look after her.”
As Sharon’s health improved and the quartet settled into their new dynamic, the advantages became increasingly apparent. Financially, the shared household proved to be a significant boon. Beyond the economic benefits, the cousins, who were once only children, have developed a strong, sibling-like bond. Crucially, having another adult to consult on parenting decisions has provided invaluable support and perspective.
“It got better and better and better, and then, before we knew it, we were like, ‘Oh my God, this is so good!’,” says Sharon. “We have such a lovely home, and the kids are so much fun. It became this really lovely family unit.” While not meticulously planned, Sharon admits, “as a Plan B, it’s bloody good.”
One of the most significant benefits of their arrangement is the sisters’ alignment on parenting styles, fostering a “low-conflict home.” Sharon elaborates on the difference compared to traditional marital dynamics: “With a husband and wife, there are agendas; there’s things going on between them. That doesn’t happen in a sister relationship. There are no games. It’s very, very simple and straightforward.”
This harmonious living situation makes perfect sense for the Gavin sisters, who have always shared an exceptionally close bond, often described as feeling more like twins than mere siblings. Their connection extends to their professional lives as well; they run a wellness brand together, which encompasses retreats, mushroom coffee products, and a podcast.
A Global Trend: Single Mothers Unite
The Gavins are not alone in their move away from the traditional nuclear family model. While such an arrangement might seem unconventional in Britain, a growing number of single mothers in China are forming alliances to reduce costs and bolster mutual support. This trend mirrors a surge in social media posts from women seeking like-minded co-parents, coinciding with a dramatic rise in divorce rates. In China, divorce rates more than tripled from 0.96 per 1,000 people in 2000 to 3.10 in 2020, with a further 25 per cent jump between 2022 and 2023 alone.
With an estimated 30 million single mothers in China, and retaining custody in approximately 80 per cent of family breakdowns, experts have noted a significant increase in women actively seeking alternative support networks and living arrangements.
“There are no games. It’s very, very simple and straightforward.”

One compelling example comes from social media platform Rednote, where a post read: “I’m hoping to find another single mom to share an apartment with, so we can take care of each other. If our children are around the same age, that would be even better – they can be companions. Those raising kids alone know how tough it is; sometimes you’re so busy you barely have time to eat.”
Jiang Mengyue, 31, has embraced this approach, now living with her three-year-old daughter alongside another single mother and her child after responding to a similar online advertisement. Mengyue echoes the Gavin sisters’ sentiments, finding the relationship “purer and simpler than marriage.”
Bridging the Gap: Co-living Services and Communities
To facilitate these evolving family structures, various platforms and services are emerging. In the United States, CoAbode is a housesharing service specifically designed to match single mothers looking to combine households. This initiative addresses a growing problem: single-earner households with children have more than doubled in the US, while housing costs have skyrocketed by over 1,000 per cent since 1970.
The benefits are multifaceted, allowing women to share expenses from two incomes and provide consistent, day-to-day support with childcare. Success stories abound, such as Heather and Carrie in Florida. After reading about CoAbode, they met and moved in together with their children. “It’s a match made in heaven for us,” Heather shared. “Our kids get along great. Emotionally, it’s been great to have someone that’s going through the same experience that you are… My new roommate and I sit up at night after the kids fall asleep and laugh and joke about some of the trials and tribulations we go through, and don’t feel so alone.”
Shawn in Washington DC highlights the positive impact of having an additional child in the household after moving in with Darcie. “Because our sons are both only children, it’s been good for them to have brotherly attention and learn that they are not the centre of the universe.” The practical co-parenting support is also invaluable: “Recently, Darcie picked up my son from school, fed and bathed him and put him to bed. And we trade off like that constantly, which makes life less stressful for both of us.”
The Organic Growth of Informal Support Networks
In Brisbane, writer and editor Brooke Maddison exemplifies the “it takes a village” mentality, albeit in a more casual, organically formed capacity. Her son was born in London before she and her ex-partner relocated to Australia. By the time their child reached six, the couple had separated. “I had some old friends, but I initially didn’t have a lot of community around me,” Brooke explains. “Then I found it happened really organically when my son started school.”
She noticed many other parents who were either single-handedly raising their children, identifying as queer, or part of non-traditional family structures. These individuals naturally gravitated towards each other. “We built up this informal community before we realised what we were doing,” Brooke recalls. “And it was like, OK, what can we do intentionally to perhaps welcome other people in and go out of our way to support each other?”
This support manifests in various ways, from ad hoc arrangements like a fellow parent stepping in for school pick-up and dinner when someone needs to work late, to more structured initiatives. Brooke has previously hosted weekly open-invitation dinners for parents and children with the explicit intention of fostering community. “I’ll cook up a massive batch of something, and then even be sending people home with tupperware containers of extra food so they’ve got an easy dinner for the next night.”
“We built up this informal community before we realised what we were doing.”

The reciprocal nature of this network is also evident. Brooke, who doesn’t drive, now has a reliable group of fellow parents who assist with grocery shopping or provide transport in emergencies. This quid pro quo arrangement has even extended to organising annual group holidays, which not only offer companionship and adult conversation after the children are asleep but also significantly reduce costs through shared transport and accommodation.
Brooke strongly advocates for proactively building such a community, especially for those raising children alone. “Sometimes it’s just having someone to talk to – if you need to call someone in the middle of the night, or if you’ve had a really tough day with the kids and need to vent,” she advises. “Sometimes a friend will ring me up for a chat, and we’ll just talk about some of the difficulties that we’re facing and really support each other emotionally.”
Redefining Family for the Modern Era
Brooke argues for an expanded societal view of what a family “should” look like in 2026, moving beyond outdated, heteronormative narratives that exclusively define family as a mother and father in a romantic partnership. “Broadly in society, that is still the expectation of how people live; we don’t see alternatives modelled that much,” she observes. “But I think things are changing.”
Her observation is accurate; the landscape of family formation is indeed evolving. Numerous fertility networks have emerged to connect individuals seeking “platonic co-parents” for the purpose of having a child. Platforms like Pollen Tree, CoParents.co.uk, and The CoParenting Agency facilitate these matches, while Modamily offers an online community for those looking to “date with purpose,” with the express intention of starting a family.
Perhaps it’s time to broaden our collective understanding of what constitutes a family in today’s world. Statistically, the nuclear family is becoming less prevalent. In the UK, approximately one in four families with dependent children (totalling two million) are single-parent households, with around 89 per cent of these being single-mother families, according to data from the charity Gingerbread.
Lauretta Gavin believes society has long overemphasised romantic love in the context of child-rearing. “There’s so much focus on, ‘you need to find the one’. That comes from the messages that we’re fed by movies, by films, by books,” she states. “There’s not enough attention on the love of a friendship, particularly female friendship. That love is often dismissed or undervalued – but it’s just as powerful.”
