Mean girls grow up. Some of them now do the school run.
A friend of mine is watching her daughter stand on the outside of a friendship group. She is standing on the outside of one too. Same school gate, same story, two generations apart.
I’m a long way from that season now, though I remember it first hand, and I sit with women in my coaching work who know what feeling excluded by other mums leaves behind, sometimes decades later. Exclusion doesn’t check your age before it leaves a mark.
When it’s your child on the outside, and you as well
In children’s friendship groups we almost expect it. Girls are still learning how belonging works, still testing where they fit. The mums are harder to explain. Grown women, with more years, more perspective, and presumably at least one memory of being the one left off the invitation.
You’ll know the moments I mean. The party invitation that goes out to ten and somehow misses two names. A WhatsApp group for an event you only hear about once it’s over. Conversations that change shape as you walk up. At first you feel it on your child’s behalf. Then the slower, colder realisation arrives: this was done to her, and it was done to you as well.
I can’t think of a single mother who wouldn’t feel the sting of that. Yet it happens over and over, carried out by women who would be wounded to find themselves on the receiving end.
Why do mums exclude other mums?
So why? Some never look. The list gets written at speed, the group chat created without a second thought, and the leaving-out happens through carelessness rather than cruelty (which hurts no less when yours is the name that got forgotten). Others do see it. For them the circle only feels safe when someone is outside it. The girls at school are working that out loud. The mums learned to do it in ways that look more polished and cut just as deep. Meanness, at any age, seems to grow in the places where we feel unsure of our own belonging.
The question underneath: do I belong here?
Lately I’ve been trying to go one layer further down, because carelessness and insecurity are only the mechanics. Underneath them sits an older question. Do I belong here? Most of us first asked it in a playground and never entirely stopped asking. The question goes dormant for years at a time, then a group chat forms without you and there it is, wide awake, using the same voice it had when you were nine. For a mother it arrives doubled. I watch my friend hold both at once: the helplessness of seeing it done to her daughter, and underneath that, her own hurt, older and more familiar than she’d like to admit (schoolgirl politics have a surprisingly long shelf life).
What our daughters learn at the school gate
Here is the part I keep circling back to. Our daughters are watching how belonging works long before anyone explains it to them. They learn it at the gate, from who we wave at and who we don’t, from which names make our lists, from the way conversations open or close when certain people walk up. When we close a circle to feel safer inside it, somebody small is taking notes.
Feeling excluded by other mums: what helps
If you’re the one on the outside right now, the first thing worth saying is that the sting is legitimate. You aren’t oversensitive, and neither is your child. Belonging matters to human beings at every age, which means exclusion registers as pain rather than preference, and pretending otherwise only sends the hurt underground, where it tends to grow teeth. Name it, to yourself at least, and ideally to one person who won’t talk you out of it. Then watch the story you attach to it. Being left off a list says something about the list. It is remarkably good at convincing you it says something about you.
If you’re the one holding the list, the ask is smaller and somehow harder. Pause before you press create on the group chat. Read the names back and notice who is missing, and whether they’re missing by accident or by comfort. Most of us aren’t cruel. Most of us are busy, and busy is where carelessness does its best work.
I don’t have a tidy answer. What I do know is that hurt doesn’t retire when we grow up, and the women doing the excluding are almost certainly carrying something too. Recognising that doesn’t excuse it. It might help us understand it.
Have you ever found yourself, or your child, on the outside of a group? I’d love to hear how you made sense of it.
