How parenthood changes a relationship
Becoming a parent is one of life’s biggest transitions. Alongside the joy, excitement and love that children bring, parenthood also changes the relationship between partners in ways that many couples don’t fully anticipate.
Every relationship begins as a dyad. Two people create something that is uniquely theirs. Together, they develop their own routines, rituals and rhythm. Attraction grows into passion, followed by limerence, that intense period where hormones and chemistry do much of the heavy lifting.
After around two years, those hormones begin to settle. Couples see each other more clearly and decide whether this is a relationship they want to build a life around. For many people, the next chapter is becoming parents.
The arrival of a child changes the dynamic
There are many kinds of “third” that can enter a relationship, but here I’m talking about a child. Imagine the disruption to that carefully balanced system. A couple has found its rhythm. Their nervous systems have begun to settle alongside one another. Then arrives this wonderful, adorable and completely disruptive little human.
Every aspect of daily life changes. Sleep, routines, priorities and responsibilities all shift. Couples begin learning how to care for another person while adapting to entirely new versions of themselves.
Parenthood asks for more from us than we expect
I sometimes wonder whether we spend enough time thinking about what parenthood actually asks of us. Do we really consider whether both partners have the emotional, practical and psychological capacity to sustain parenting, not just during the newborn months, but over the next twenty years?
Parenthood stretches far beyond welcoming a baby into the world. It includes sleep deprivation, endless noise, constant decision making, toddlerhood, school years, developmental surprises, financial pressures and a level of responsibility that continues well into adulthood. These experiences shape every member of the family, including the couple themselves.
Why parenthood can feel so challenging for couples
The demands of family life place enormous pressure on even the strongest relationships. Exhaustion, anxiety, housing, careers, childcare, school choices and finances all compete for time and attention. Partners are often trying to meet everyone’s needs while finding very little space for each other.
I work with countless couples who absolutely adore their children. They care deeply about creating the best possible family life. At the same time, parenting together asks two adults with different parenting styles, different tolerances and different emotional capacities to work together every single day. It’s one of the biggest collaborative challenges any relationship will face.
Playing to each other’s strengths
One conversation I encourage couples to have is about capacity rather than comparison. Ask yourselves:
- What am I genuinely good at as a parent?
- What do I find more challenging?
- Where does my partner naturally have more capacity?
Every parent brings different strengths into family life. Recognising those differences allows couples to work together more effectively, reduce resentment and support one another in ways that feel sustainable.
The goal is to build a partnership where both people contribute in the ways they are best able.
Preparing for parenthood as a couple
One thing I encourage couples to do before becoming parents is to have honest conversations about expectations. Research from The Gottman Institute found that around two-thirds of couples experience a significant decline in relationship satisfaction during the first three years after welcoming their first baby. While every family’s experience is different, the findings highlight the value of preparing for parenthood as a couple before life becomes busier and more demanding.
How do you each imagine family life? What does sharing the workload look like? How were you parented, and which parts of that experience would you like to carry forward or leave behind? This also links to your inherited relationship scripts.
Many of us arrive at parenthood with assumptions we have never spoken aloud. One partner may expect to divide responsibilities equally, while the other naturally takes on more without realising it. Some people need structure and routine, while others are more comfortable adapting as they go.

“Many of us arrive at parenthood with assumptions we have never spoken aloud…”
Talking openly about values, roles, finances, boundaries, support networks and how you each cope under pressure creates a stronger foundation for the years ahead. Those conversations won’t remove every challenge, but they can help couples approach parenthood as a team from the beginning.
Keep investing in your relationship
As family life becomes busier, many couples pour their energy into providing for everyone else. Children, work, finances and daily responsibilities naturally take priority, while the relationship gradually receives less time and attention.
When I ask couples whether they’ve done the homework for their relationship, I often hear:
“Sorry, Karen… life just got in the way.”
It’s an understandable response. Family life is demanding. Yet relationships need nurturing too. They thrive on conversation, affection, shared experiences and moments of genuine connection. Even small acts of kindness help couples feel like partners rather than simply co-parents.
A strong relationship has whole-family benefits
Children gain so much from growing up in a home where they see warmth, kindness and affection between the people they love most. They benefit from hearing laughter, witnessing respect and experiencing a home that feels emotionally safe. Those everyday moments help shape their understanding of healthy relationships long into adulthood.
Looking after your relationship is part of looking after your family. By making time for each other, staying connected and continuing to communicate openly, you’re creating an environment where everyone can flourish.
Be intentional. Keep talking. Show appreciation. Choose kindness whenever you can. Your relationship deserves care, and your children benefit from seeing it.
