Why does everything feel like an argument after having children?

Have you felt like you can't seem to find any common ground with your partner since having children? Like the smallest disagreement can turn into days, or even weeks, of resentment?

It's one of the most common conversations I have with the couples and parents I work with. In fact, it's probably one of the biggest topics that comes up whenever I'm chatting to friends with young children too.

The first thing I want to reassure you is that this is incredibly common. It's usually not that you're arguing more because you love each other less. More often, it's because parenting is hard. You're trying to juggle work, childcare, housework, the mental load and a never-ending to-do list, often on very little sleep. When you're both running on empty, even the smallest disagreement can quickly snowball into feeling like something much bigger.

Why parenting changes your relationship

It's not just exhaustion. We are all flawed humans, and parenting means trying to raise children alongside another flawed human being who has had a completely different upbringing, different experiences and different ideas about what family life should look like. Before children, many of those differences don't really matter. Once you're making hundreds of parenting decisions every week, they suddenly become impossible to ignore.

How do we handle tantrums? How much screen time is OK? Should we be strict or more relaxed? Who gets up in the night? How tidy should the house be? How do we spend our money? Even the way we show affection, deal with stress or communicate when we're overwhelmed can be very different.

What's interesting is that we spend months preparing for pregnancy and birth. We read the books, buy the equipment, decorate the nursery and pack the hospital bag. Yet very few of us spend any time talking about how we're actually going to parent together. We rarely have conversations about our values, our expectations or how we'll navigate the inevitable moments when we disagree.

So when those differences begin to surface, it's easy to assume something must be wrong with the relationship, when often it's simply two people trying to navigate one of life's biggest transitions without a roadmap, and with communication skills that were probably never modelled to either of them in the first place.

Why every disagreement feels bigger

The other challenge is that once you have children, there's rarely time to make up properly. Before you've had a chance to talk things through, one of the children needs you, someone has to make dinner, bedtime begins, or you're both rushing off to work. The disagreement gets deprioritised rather than repaired, and those small moments slowly turn into resentment.

That's often when the voice in our head starts getting louder.

It starts asking questions like, "Have we grown apart?" "Have we fallen out of love?" "Have I chosen the wrong person?" or "Is this just what relationships are like once you have children?"

When we're exhausted and overwhelmed, our brains naturally become much better at spotting problems than possibilities. It's easy to start catastrophising and assuming the arguments must mean something much bigger about the relationship itself. So many couples say to me, "We never used to be like this."

And they're right. Life isn't the same as it was before children. Before children, there was usually more time to recover after an argument. More opportunities to laugh things off, spend time together and reconnect before life got in the way again. Now it's easy to start feeling more like housemates running a family business than the couple you used to be.

You're not on opposite teams

One of the things I often remind couples is that most people don't become more loving when they feel criticised. They become defensive. I know that was certainly true in my own relationship.

When I first went to couples therapy, if I'm honest, I thought my husband was the problem. I wanted him to understand how much I was doing and why I felt so exhausted. And some of that was absolutely true.

But what I hadn't realised was that he had his own fears and vulnerabilities too. He wanted to feel appreciated. I wanted to feel understood. The more criticised he felt, the more defensive he became. The more defensive he became, the more alone I felt. We were both trying to protect ourselves, but neither of us felt safe enough to really hear the other.

It wasn't until we started understanding each other's attachment histories and the stories we'd both been carrying long before we became parents that things began to change. I learnt that if I approached him with curiosity instead of criticism, he was much more able to hear what I was trying to say. He learnt that because of my own experiences, I'm incredibly sensitive to criticism and often hear rejection where none is intended.

Neither of us was the problem. The cycle was. Once we stopped trying to win the argument and started trying to understand each other, it became so much easier to find our way back to being on the same team.

Three things to remember when you're struggling

If you've recognised yourself in this article, I'd love to leave you with three takeaways.

1. Don't believe every story your brain tells you

When we're overwhelmed, our brains become brilliant at filling in the gaps, and they rarely fill them with the most generous explanation.

For the next week, notice the thoughts that pop into your head during or after an argument:

• "They don't care."
• "I'm doing everything."
• "I'm not important."
• "They think I'm a terrible parent."

Then gently ask yourself: "Do I know that's true, or is that the story my exhausted brain has created?" If you're feeling brave, ask your partner too. "When you said that, this is what I made it mean. Is that what you meant?" You might be surprised by the answer.

2. Remember that this feels hard because it is hard

Having children changes almost every part of your relationship. Your routines, your roles, your priorities, your identity and the amount of time you have for one another all shift, often overnight.

If you're finding this season difficult, it doesn't automatically mean you've chosen the wrong partner or that your relationship is broken. It means you're doing something incredibly hard.

Try to offer yourselves the same compassion you so easily give your children.

3. Expect change to feel awkward

One of the biggest mistakes I see couples make is trying something different once, only to give up because it doesn't immediately change everything.

Perhaps you respond more calmly, and your partner is still defensive. Maybe you make more of an effort to show appreciation, and it isn't received in the way you'd hoped. That doesn't mean it isn't working.

When we've been stuck in the same pattern for months or even years, it takes time for both people to trust that something has genuinely changed. New ways of communicating often feel uncomfortable before they feel natural because they leave us feeling vulnerable.

Keep going.

The strongest relationships aren't built by two perfect people who never argue. They're built by two imperfect people who keep choosing to get curious, to repair, and to find their way back to each other. Because just like parenting, relationships don't need perfection. They need repair.
