When you're in the thick of twin toddlerhood — surviving on multiple caffeinated drinks and sleep deprivation (thanks night terrors!), negotiating with two irrational toddlers simultaneously, and quietly weeping at your childcare costs — the idea of adding a third child sounds either brave or unhinged. Possibly both.
We were there. The first 18 months of twins were brutal. We love, love, love our twin boys, but it was brutal. Yet, they had just turned 2 years old and we were in this really fun phase, and dare we say it….we considered whether we should have another kid.
I'd always wanted a big family. But by the time we were even entertaining the idea, we were both in our late 30s. We were more financially stable than we'd ever been, which was great — but the energy reserves? We had almost unlimited energy in our 20s. Four hours of sleep after going out at night and surviving at work? Easy. Early 30s was a little harder, but mid-late 30s, especially with twin toddlers was brutal.
So, given our ability to survive with very little sleep at our current age, it was basically now or never. We had to actually sit down and figure out if "now" was a good idea or just a sleep-deprived fantasy.
Here's what we wrestled with (and now that we do have a third, what you might want to consider).
We were already dividing attention between two kids. Adding a third meant we had to switch from man-on-man coverage to zone defense. Would everyone feel like they were getting enough of us? Could we even pull that off?
We were already very humbled by taking care of two toddlers. We needed to think hard about what age gap made sense — how can we juggle a newborn's needs while also managing two toddlers who have very strong opinions, feelings, and volume. One thing we did make sure was that our twins would be completely potty-trained before I got pregnant, and if that didn't work, at least before the baby came. There was no way we wanted to be changing 3 kids' diapers. Can you imagine the diaper budget?
Childcare costs are genuinely absurd where we live, and we knew a third meant that we’d have overlap in childcare costs for a while. After a lot of back-and-forth, we landed on an ideal spacing where the baby would arrive when the boys were 3 to 4 — meaning only about one to two years of three kids in childcare simultaneously. Not ideal, but survivable. Date nights just got a lot more expensive, because babysitters (if you're lucky enough to even find one who wants to take on two toddlers and an infant) charge more for 3. I mean, with the cost, we could just retire a few years later right? No seriously, that’s what we decided was worth the tradeoff.
As the twins get older, it gets so much easier on us. At 3.5, they became signficantly less dependant on us for things like getting into their carseats, eating dinner, etc. They can get dressed on their own in the morning and use the potty. They clean up (very generous use of clean up) after dinner and put their dishes in the dishwasher. They play together while we cook dinner (yay! economies of scale) and don't need our attention 24/7. One parent can take both of them out to a restaurant. They also have more activities (gymnastics class, art class, sports, etc.) where one parent can take them and spend quality time with them without feeling overwhelmed.
We love our twin boys more than anything and we’re so excited that they get to grow up with their best friend beside them — but we were also, quietly, a little terrified of having a second set. The first 18 months of twin life were brutal on sleep in a way that's hard to fully explain to people who haven't lived it.
We had identical twins from a single embryo transfer during IVF, which actually put our odds of twins again on the lower end compared to fraternal twin pregnancies. However, for mothers over 35 or going through IVF, there’s a higher probability of twins. Overall rates twins hover around 3% and for fraternal twin moms, some estimates put the odds as high as 1 in 12 for their second set.
We noted those numbers, took a breath, and proceeded cautiously optimistic. We survived twin parenthood once, and we felt like we could handle it again if it came down to it. We would simply just move in with the grandparents (the grandparents didn’t know this was an actual consideration but it kept us sane-ish 😂)
This one snuck up on us. With three kids in car seats and both of us commuting far for work, we quickly realized we needed two cars with three rows — not one. Some parents manage to fit three car seats across a single row, and honestly, we still don't fully understand how. Between a baby stroller, all the gear, and a reasonably tall spouse, we needed that third row to stay sane.
Luckily, we already had a Toyota Sienna minivan (more on why it's the greatest car ever made for twin parents in a future post), so we only needed to add one more three-row vehicle to the fleet. Once parental leave ended, the logistics plan was simple: one parent owns all the morning drop-offs, the other handles all the pickups. With long commutes on for both of us, trying to do both in one day and work a full-time job just wasn't realistic.
Our boys shared a bedroom. Was it fair that the baby got her own space with a dedicated nursery? We braced ourselves for the negotiation. Instead, our twins immediately announced that the baby should share a room with them, because obviously she'd want to be near them. I didn't expect to get emotional about a bedroom logistics conversation, but here we are. We had just moved our toddlers to “big kid” beds before starting the third kid conversation, so that helped a bit.
We did our homework, talked to friends who'd been through it and read the internet's collective wisdom. A few things genuinely made a difference.
Before she arrived, we got the boys personalized books from Wonderbly and Hooray Heroes about their new trio and non-personalized books from Amazon about becoming a big sibling. Here are three that we ordered from Amazon (The New Baby, I am a Big Brother, and Big Brother Daniel (from Daniel Tiger)). We read them at bedtime and talked up what an incredible thing it was going to be — a new best friend that would go on so many adventures with them! The new BFF hype campaign worked. When I arrived home from the hospital, I came bearing gift bags full of new toy activities for the boys (crafts, etc.) from the baby, so it made them so excited and also kept them occupied.
We were intentional about carving out special time with each of the boys, separately, before and after the baby was born. The goal was making sure that all the attention suddenly swirling around the baby didn't make them feel like they'd been demoted.
This one sounds small but it matters a lot. Instead of "please be quiet, the baby is sleeping" (which quietly teaches them that the baby is the reason they can't have things), we shifted to "mommy's ears hurt when it's really loud" or "I'm in the middle of something and I'll be with you in a few minutes." You don't want to accidentally set up a rivalry before she can even hold her head up. It’s the kids that are one team vs. mom and dad, if anything. One team, one dream.
One unexpected upside of the age gap: baby gear has genuinely gotten better. After three years away from newborn life, I came back with fresh eyes — and a very clear sense of what had worked before, what hadn't, and where I wanted to make upgrades. With even less time on our hands now, I was deliberate about investing in gear that bought back some of it.
The biggest time saver? Automatic bottle washers. An absolute game changer for anyone who has suffered through the dry, cracked hands that come with washing tiny bottle parts multiple times a day, then moving them to the sterilizer, and then the drying rack. If you know, you know. I also completely rethought how the nursery and feeding station were organized — if you want to see the full setup, I wrote a whole post about the organization system. Fewer chores, more sleeping. That's the goal.
Oh, and one more thing nobody told me was a bonus of having a third singleotn baby: singleton strollers are so light. After years of hauling a twin stroller down flights of stairs like I was moving furniture, picking up a single stroller felt EASY. Genuinely one of the most underrated perks of having just one baby at a time.
Honestly? Better than we feared. Not without hard moments — but better.
The 3.5-year gap turned out to be the right call for us. Threenagers are already a full-time emotional management job, but at that age they could understand (somewhat) that babies have needs. They knew to be gentle. They had enough language and enough development to process what was happening, even if they didn't always love it.
The toughest part was the first few weeks. Our twins had always been more attached to me, and suddenly I was the one spending most of my time with the newborn while my husband took the lead with them. They felt it. There was more acting out — messier dinners, some hitting, general chaos — all the classic signs of big feelings with nowhere good to go yet.
Once I was more recovered, we switched. I took the boys on "mommy dates" while my husband watched the baby. That helped enormously. They just needed to know they still had me and I wanted to spend time with them.
And then something shifted. As the baby got more interactive and started cooing, they got obsessed with her. They want to help me out with the baby. They race to grab burp cloths. They hold her bottle and tell her how cute she is. They draw pictures for her nursery wall. The protectiveness and pride they feel for her is one of the most genuinely lovely things I've ever watched.
As for our third? She is the chillest baby. I'm convinced she spent nine months listening to the noise of a house with twin toddler boys and simply prepared herself. She's patient. She's intrigued by all the chaos around her. She fits right in. We somehow got really lucky.
Would we do it again? Yes. Was it a lot? Also yes. But watching three kids who are completely in love with each other grow up together — that part we didn't have to talk ourselves into at all.
Also, the age-old question every twin parent wants to know. Is having a singleton that much easier than having twins? I can now speak from experience and say 100% yes. It's like 2x easier. But then, if you want to ask me how hard is it having twin toddlers and a baby...
