I remember being at a friend’s birthday party a year ago, chatting with a mom of two, when my jaw completely dislocated from my face, rolled across the floor, and became the dog’s new chew toy (hyperbolic). I had a 1.5-year-old and was pregnant with my daughter at the time. This mom also had a toddler son and a baby daughter. And when I asked her if she was done having kids, she immediately said no — and I was fucking floored.
As a [age redacted] mom, I can attest that no topic hijacks group chats, preschool pickup lines, and wine nights quite like the “two vs. three kids” debate. It’s something we whisper about only after making sure our partners aren’t listening and double-checking our pregnancy apps to confirm we didn’t miss a period.
Everyone tells me the same thing: “You have one of each!” (Meaning a boy and a girl. Groundbreaking. Pulitzer-worthy observation.) “How lucky!” (Mmm? Thanks?) “You can stop now!” (Appreciate the permission, random person.) And truthfully, I thought I would be done. I did want one of each (which is silly, because gender is a social construct, etc., etc.). And I did think if I got that, I would stop. But not even four weeks after my daughter was born, I started getting the itch. The maybe-I-should-have-another itch.

Two feels manageable. Two makes sense. One per parent, one per hand, one per side of the double stroller. But then you start thinking… maybe there’s room for one more? Maybe your family isn’t complete yet? And suddenly you’re Googling “best cars for a third car seat” in the middle of the night and wondering if your sanity can stretch as far as a minivan.
Parents who stop at two swear it’s the sweet spot: logistically reasonable, somewhat predictable, and still possible to travel without needing an extra hotel room. But parents who go for three insist it’s the best gift they ever gave their kids — built-in best friends, new sibling bonds, and a weird sense of confidence that comes once you’ve already survived the baby stage a couple times.
The catch? Nobody agrees on which option is actually easier. Some say zero to one was the biggest shock to the system, others claim going from two to three is what really broke them, and everyone seems to have a horror story about juggling school schedules, snack rotations, and childcare costs.
So… is “two and through” the smart move? Or is more actually merrier (and by merrier we mean louder, stickier, and exponentially more expensive)? To get answers, we asked both experts and moms in the trenches to spill.
The Case for Stopping at Two Kids
Let’s math it out: two kids are less than three kids. Hard stop. Less time split, less money spent, fewer humans to keep alive, and (hopefully) turn into decent adults. But stopping at two isn’t just about survival — it’s about control (or at least the illusion of it). With two, you can still tag-team bedtime. You can split up school drop-offs without needing a third adult. You can even *gasp* imagine going on a vacation that doesn’t require a sprinter van.
“Parents often decide to stop at two because of practical considerations like finances and support systems,” says Robin Hilmantel, mom of three and senior director at What to Expect. “Families with multiple children tell us they’re happy with their decisions (or at least too sleep-deprived to fight them anymore). It tends to be something that families make peace with and learn to appreciate.”
And it’s not just money — it’s energy. Sipra Laddha, MD, a board-certified physician in perinatal psychiatry (oh, AND mom of four), notes that the jump from one to two is often the hardest: suddenly you’re dividing your attention, and once you’ve found a rhythm, you might not want to blow it up again.
For many parents, two translates to balance: two kids, two hands, two car seats that still fit in a sedan. Not exactly easy, it’s manageable enough that you’re not Googling “does Target sell bulk Xanax” every other week.
And sure, some parents do one-and-done. A trend that’s rising, with family size shrinking from 2.44 kids in 1965 to 1.94 in 2023. (Why? Lack of support, no paid leave, general sense the world’s ending — take your pick.) That’s its own whole debate, but experts say only children do just fine developmentally, often thriving under more focused parental attention. Do with that what you will.
The Case for Adding a Third (Or More)
For some parents, two kids just feels… unfinished. There’s this gut-level sense that someone is missing from the dinner table, even if your hands (and calendar, and wallet) are already full.
Jessica H., 37, described it like this: “After our second child was born, my husband and I just had this feeling that our family wasn’t complete.” With three, she says there’s actually more confidence: “You know that your child eating a Cheerio off the floor won’t kill them. You know that silence means someone is up to something. You know that they will reach their milestones when they reach them. For us, adding more kids was a shift to the system, not a shock.”
Even parents who didn’t plan on three often admit it worked out. Sara T., 34, was perfectly content with two when she got a surprise positive pregnancy test. “We thought having a third child would make things so hard, but she actually leveled our family out and brought peace into our home,” she says. “I would choose three kids vs. two kids over and over again.”
Hilmantel says she had a similar experience herself: “The jump from two to three kids felt less challenging because we already had routines and rituals in place that made sense for multiple children.” Many parents in the What to Expect (and the Betches Moms one, FWIW) community echo the same sentiment: adding another can feel like less of a shock to the system than that very first leap into parenthood, which makes sense because you’ve already been broken by sleep deprivation more than once.
Experts agree there can be major benefits to going bigger. “The pros for having two versus three versus more kids is that there is often the earlier ability to develop a peer-like network as well as learn to adapt and negotiate with others around you,” explains Dr. Laddha. You know what they say: nothing builds conflict-resolution skills like three siblings screaming over the last crumpled granola bar that none of them actually like.
When “More” Might Actually Be Too Much
Of course, not every family that goes beyond two ends up feeling like they made the right call — and that’s okay to admit out loud. Especially because there are a million moms out there frantically searching “should I have another baby reddit” at 2 am instead of sleeping.
Audrey C., 33, says she went for a third, hoping for a girl, and got another boy. “It got exponentially more expensive… childcare costs have gone up SO much. I feel like a triage nurse constantly deciding who needs the most attention.” While she loves seeing the sibling bonds play out, she admits, “If it were just about the number, I think I would have stuck with two.”
An anonymous mom of five agrees: “Growing up with siblings is the best thing — you literally have built-in best friends. But truthfully, if I could go back in time, I’d probably stop at three kids. Not because I don’t love them, but it’s hard to provide for a big family nowadays without having to work twice as hard.”
Experts say these feelings are common (and def not something to be ashamed of). “Every family has limits on time, attention, stimulation preferences, and finances,” says Dr. Sipra Laddha. “At any point where adding another child consistently exceeds capacity in one of these areas, it can have a negative impact on the family dynamic.” That said, you prob shouldn’t tell your extra kids that you regret having them and they made your life awful, but what do I know?!
Robin Hilmantel adds that mental health should always be part of the equation. “If parents are struggling already with the demands of child rearing, that’s an important factor to keep in mind before having another. We strongly advocate for parents to take care of their mental health, seek professional help when needed, and see if their village can step in to help them carry the load.”
In other words, adding more kids doesn’t automatically equal more love and joy — sometimes it just equals more laundry, more bills, and more meltdowns (yours included). And if you’re wondering whether to roll the dice again, experts agree it’s worth asking yourself if you really want to shake up a system that’s already (somewhat) working… or if you just want to sniff a baby head (that will eventually grow up and move away and forget to call you back and OMG now I’m crying).
But What About Middle Child Syndrome?
Ah yes, the classic reason people avoid having three: nobody wants to “ruin” their second kid. Here’s the thing — experts say it’s not that simple. “There is some evidence supporting stereotypes about birth order, like that younger siblings may be less risk-averse and more extroverted,” says Hilmantel. “But the significance of these attributes is debatable, so parents should take it with a grain of salt.”
Dr. Laddha agrees: “Birth order does play a role in how kids’ lives and personalities are shaped. Not all middle children have ‘middle child syndrome,’ but certainly many of them have similar struggles between the oldest and the youngest.” Translation: your second kid isn’t doomed to a life of being overlooked… unless you actually overlook them.
So, How TF Do You Figure Out Your Ideal Family Size?
After all this back-and-forth, here’s the anticlimactic truth: there is no universal “perfect number.” Sorry! I have asked thousands of IRL moms and grandmas and experts, and honestly? The ideal family size is the one that doesn’t push you past your emotional, financial, or logistical limits.
The hard part is figuring out what TF that limit is without going past it and being like, “oops, shouldn’t have had that last kid, my b.” Many families opt for a “2 yeses = yes, 1 no and 1 yes = no” approach: if one person wants another baby and the other doesn’t (or is on the fence), they don’t — because, duh?
“Parents can figure out what’s right by taking an honest look at their current feelings and acknowledging their limits,” Dr. Laddha says. “There really is no perfect number, and no perfect situation. The number predictor is both parents being aligned in their vision for their family and being honest with each other and themselves about capacity in different areas of their lives.”
Hilmantel agrees, adding that the ideal family size often changes over time: “Sometimes your plan changes down the road, and that’s okay. If you’re happy and satisfied, the ideal family size will be the one you end up with.”
As Dr. Laddha likes to say, “wherever you go, there you are.” If you’re already struggling with the number of kids you have (whether it’s in your marriage, your money, or your mental health), adding more probablyyyy won’t solve your issues. But if you do keep going, your best course of action is to simply embrace the chaos and let go of the idea of control. Because honestly? You never really had it to begin with.
In other words, whether you’re one-and-done, two-and-through, or slowly assembling your own modern-day Brady Bunch reboot with a less bitchy Marcia and hopefully better lighting, the only right number of kids is the one that keeps you semi-sane (or if you went past that number, then the number of kids you have now is solid, I guess). And if you’re still spiraling at 2 am about whether to add another until you’re well into your retirement? Join the club — at least all of us moms on Reddit will keep you company.
