Having twins is significantly harder than having a single baby, and the difficulty shows up at nearly every stage: pregnancy, birth, postpartum recovery, sleep, feeding, finances, and the toll on your relationship. That doesn’t mean it’s unmanageable, but the challenges are real and measurable. Understanding what makes twins harder, and by how much, can help you prepare rather than be blindsided.
A Harder Pregnancy From the Start
Twin pregnancies carry roughly double the risk of several major complications. In a large study comparing over 6,000 twin pregnancies to more than 357,000 singleton pregnancies, 10.6% of twin mothers developed pregnancy-related hypertensive disorders (including preeclampsia) compared to 4.7% of singleton mothers. Gestational diabetes affected 8.4% of twin mothers versus 4.8% of those carrying one baby. These aren’t small differences, and they mean more monitoring, more appointments, and more time spent worrying.
Weight gain expectations are also substantially higher. For women at a normal pre-pregnancy weight, the recommended gain for a twin pregnancy is 37 to 54 pounds, compared to 25 to 35 pounds for a singleton. Overweight women carrying twins are advised to gain 31 to 50 pounds, and obese women 25 to 42 pounds. That extra weight, combined with a larger uterus pressing on your organs, makes the physical discomfort of late pregnancy considerably more intense.
Earlier Births and More Time in the NICU
Most twin pregnancies don’t make it to the standard 40-week mark. The average twin delivery happens around 36 weeks, and a little more than half of twin pregnancies end before 37 weeks, which is the clinical threshold for preterm birth. Depending on the type of twin pregnancy, delivery can range anywhere from 32 to 38 weeks.
Earlier arrivals often mean time in the neonatal intensive care unit. In 2023, 43% of babies born in multiple-gestation deliveries were admitted to a NICU, compared to just 9% of singletons. For parents, this can mean days or weeks of visiting the hospital after the mother has been discharged, pumping milk around the clock, and dealing with the emotional strain of not being able to bring your babies home right away.
Sleep Deprivation Hits Harder and Faster
Every new parent loses sleep, but twin parents lose more of it and for longer stretches. In a study tracking sleep patterns after twins came home from the hospital, fathers averaged just 5.4 hours of nighttime sleep and 5.8 hours total in a 24-hour period at two weeks postpartum. Mothers fared slightly better at 6.2 hours of nighttime sleep and 6.9 hours over 24 hours, but their sleep was heavily fragmented, broken into short stretches by the alternating needs of two infants.
Sleep efficiency did improve over the first 20 weeks, but the improvement was gradual. The fragmented nature of the sleep matters as much as the total hours. Getting six hours in 90-minute chunks is not the same as six continuous hours. This kind of chronic, broken sleep affects mood, decision-making, and patience in ways that compound over weeks and months.
Feeding Two Babies at Once
Breastfeeding twins is possible but dramatically harder than feeding one baby. Globally, exclusive breastfeeding rates among twins range from just 4% to 22%, compared to about 48% for singletons. The gap is enormous, and the reasons are practical rather than biological.
Mothers of twins face a long list of overlapping barriers: sessions that take twice as long, difficulty finding positions that work for two babies simultaneously, exhaustion that undermines milk supply, and the reality that premature twins may need to start with pumped milk or formula before they can latch effectively. Privacy concerns make tandem feeding (nursing both at once) uncomfortable for many mothers, but feeding one at a time can mean spending the majority of your waking hours doing nothing but nursing. Many twin parents end up using a combination of breast milk and formula simply to survive the logistics.
The Financial Reality
Twins don’t cost exactly double, but they come close in the first year. For a middle-income family, first-year costs for twins were estimated at roughly $25,880, compared to about $12,680 for a single baby’s first year. The biggest single expense is childcare, which jumped from about $2,870 for one baby to $6,180 for twins. Clothing and diapers nearly doubled from $750 to $1,580, and food costs were $2,900 in the first year alone.
Some costs don’t double cleanly. You don’t need two cribs in two separate rooms. You can reuse certain gear. But the items that scale with the number of children, like diapers, formula, daycare slots, and car seats, add up quickly. The financial pressure is often most intense during the period when one parent may have reduced income due to leave or a decision to stay home, which itself becomes a more common consideration when childcare for two infants costs more than some people’s mortgage payments.
Relationship Stress and Mental Health
The strain on a partnership is one of the less discussed but very real difficulties of having twins. Research on parents of multiples has found that the number of children born at once significantly affects marital satisfaction, with mothers reporting the impact more strongly than fathers. Material needs, social stigma, and reduced quality of life all showed significant associations with having multiples. The combination of financial pressure, sleep deprivation, and the sheer volume of caregiving leaves less time and energy for the relationship itself.
Postpartum depression is also more common. Mothers of twins have about a 24% higher risk of developing postpartum depression within the first six months compared to mothers of singletons. For fathers, the increase was smaller (about 11%) and not statistically conclusive, but the trend pointed in the same direction. The risk isn’t dramatically higher for any individual parent, but it’s elevated enough that both partners should be aware of the signs: persistent sadness, withdrawal, difficulty bonding, or feelings of being overwhelmed that don’t improve with rest.
Development Usually Catches Up
One common worry for twin parents is whether their children will hit milestones on time. The picture here is more reassuring than most of the other challenges. When researchers account for the fact that twins are often born earlier and smaller, the developmental differences between twins and singletons largely disappear in the early years. Studies of preterm twins and singletons found no significant differences in cognitive ability or functional disability when assessed at ages two and three, once gestational age was factored in.
There is some evidence that twins may score slightly lower on language and reading measures around age seven, even after adjusting for prematurity and birth weight. This likely reflects the reality that twins share their parents’ attention and verbal interaction in ways singletons don’t. But these differences are modest, and they don’t indicate a developmental disorder. Twins tend to catch up, and many develop a rich language environment with each other that standardized tests don’t capture.
What Actually Makes It Manageable
The parents who cope best with twins tend to share a few strategies. They accept help early and often, whether from family, friends, or paid support. They let go of expectations about how things “should” look, particularly around breastfeeding, housekeeping, and getting back to normal quickly. They prioritize sleep in shifts, with each parent taking a defined block of uninterrupted rest rather than both waking for every feeding.
Getting on a synchronized schedule is the single most repeated piece of advice from experienced twin parents. When one baby wakes to eat, you wake the other. It feels counterintuitive to disturb a sleeping infant, but the alternative is never having a break at all. Twins who eat and sleep on roughly the same schedule give their parents windows of time that don’t exist otherwise.
Having twins is genuinely hard in ways that are quantifiable: more complications, less sleep, higher costs, greater mental health risk. But millions of families do it every year, and the intensity of the early months does ease. The first year is a survival phase. Most twin parents will tell you it gets meaningfully easier once both children sleep through the night, and easier again once they can entertain each other, which is a benefit singleton parents never get.
