Most married couples with children have sex somewhere between once a week and twice a month. In a large survey of parents, 44.5% reported having sex one to two times per month, while 30% reported one to two times per week. That leaves a wide spread on either end: a small number have sex daily, and about 3.5% say they never do. If you searched this question hoping to figure out whether your own frequency is “normal,” chances are it falls right in that range.
How Children’s Ages Change the Numbers
The age of your youngest child is one of the strongest predictors of how often you’re having sex. Parents with babies under 1 year old have the lowest frequency. Only about 2% of parents with infants report having sex daily or three to four times a week. The odds of having sex at least once a week during the first six months after a baby arrives sit around 27 to 28%, rising slightly to 33% between months seven and twelve.
Things pick up as kids grow. Once children pass age 5, about 6.8% of parents report sex at daily or near-daily levels, and the probability of weekly sex climbs to roughly 43%. That shift makes intuitive sense: older children sleep through the night, require less physical caregiving, and give parents more evening hours to themselves. The trajectory isn’t perfectly linear, though. Frequency tends to plateau when kids are between 1 and 2, then rises more noticeably after that.
The First Year After a Baby
The postpartum period deserves its own discussion because the drop in sexual activity is steep and temporary. At one month postpartum, only about 19% of couples are having intercourse at all. Most couples resume sex around seven weeks after delivery, and by four months postpartum roughly 90% are sexually active again. By twelve months, frequency looks similar to pre-baby levels for many couples.
Breastfeeding plays a measurable role. Women who were breastfeeding at the four-month mark reported significantly less sexual activity and lower sexual satisfaction than those who were not. Hormonal changes during lactation lower estrogen, which can reduce desire and cause physical discomfort. Whether you delivered vaginally or by cesarean section matters less than you might expect. Research found few differences between the two groups, though cesarean-section mothers tended to resume intercourse slightly earlier.
How Parents Compare to Non-Parents
New parents do report lower sexual satisfaction, lower desire, and higher sexual distress compared to similar couples without children. But that gap narrows faster than many people assume. One study tracking couples from birth through the first year found that by six months postpartum, there was no measurable difference in sexual frequency between new parents and a control group of community couples. The frequency itself recovered relatively quickly; it was satisfaction and desire that took longer to bounce back, remaining lower at all time points through the first year, even as the differences became less pronounced.
A Broader Decline Beyond Parenting
It’s worth knowing that sexual frequency has been falling across the board, not just among parents. In 1990, 55% of American adults aged 18 to 64 reported having sex at least once a week. By 2010 that number dipped below 50%. In 2024, it dropped to just 37%. Researchers call this the “sex recession,” and it cuts across marital status and parenting status alike. Screens, longer work hours, rising stress, and changing social habits all appear to play a role. So if your frequency feels lower than you’d expect, you’re part of a much larger trend.
Does More Sex Mean a Happier Marriage?
The relationship between frequency and happiness is real but more nuanced than “more is better.” A well-known experiment asked couples to double their sexual frequency and then measured their happiness. It didn’t go up. The researchers found that forcing a higher frequency actually reduced the quality of each encounter, which canceled out any benefit from having sex more often. The takeaway: couples who choose their own pace tend to land at a frequency that already reflects their optimal balance. Artificially pushing that number higher doesn’t help.
What does seem to matter is the gap between partners’ desires. When one person wants sex significantly more or less often than the other, it becomes a risk factor for relationship instability. Among first-time parents studied four years after their child’s birth, fewer than half (45.7%) described themselves as sexually content. Fathers consistently reported higher desire than mothers but lower sexual satisfaction, while mothers tended to be more satisfied with the relationship overall despite wanting sex less often. That mismatch, rather than the raw number of times per month, is what tends to create friction.
What Actually Gets in the Way
Parents consistently point to the same handful of obstacles. Physical exhaustion ranks at or near the top in virtually every survey on the topic. Caring for young children is relentlessly physical, and by the time kids are in bed, many parents have nothing left. Sleep deprivation compounds this: parents of infants lose hundreds of hours of sleep in the first year, and chronic sleep debt suppresses desire in both men and women.
Stress is the other major factor. Financial pressure, the mental load of managing a household, and the identity shift that comes with new parenthood all compete for the emotional bandwidth that intimacy requires. For many couples, the issue isn’t a lack of attraction or even a lack of interest. It’s that desire needs a minimum threshold of rest and mental space to surface, and parenting young children regularly pushes people below that threshold.
Touch fatigue is a less discussed but common experience, particularly for mothers of young children. After a day of being physically needed (nursing, carrying, comforting), some parents feel “touched out” and crave personal space rather than more physical contact. This is a normal neurological response to sustained physical demand, not a reflection of how someone feels about their partner.
Putting the Numbers in Context
If you’re having sex once or twice a month with young kids in the house, you’re squarely in the majority. If it’s once a week, you’re on the higher end of the curve for parents. If it’s been a dry spell of several weeks or longer, especially in the first year postpartum, that’s also common and not a sign that something is broken. The numbers shift meaningfully as children get older, and most couples see a natural rebound without any intervention beyond time and sleep. The frequency that works for your relationship is the one where both partners feel reasonably connected, not the one that matches a national average.
