At 25 weeks, most pregnant people feel their baby move multiple times each day, but there is no single number that qualifies as “normal.” Babies at this stage are in a period of high spontaneous movement, with random bursts of kicking, stretching, and rolling that haven’t yet settled into predictable cycles. The wide range of what’s considered healthy at this point surprises many expectant parents, partly because you only feel a fraction of the movements actually taking place inside the uterus.
What Kinds of Movement Happen at 25 Weeks
By the middle of the second trimester, a fetus has a surprisingly rich movement repertoire. Ultrasound studies have documented general body movements, breathing-like motions, hiccups, startles, stretches, hand-to-face contacts, jaw movements, head rotations, and even yawning and tongue movements.1Early Human Development. Classification and quantitative aspects of fetal movements during the second half of normal pregnancy Not all of these feel the same from the outside. Hiccups, for example, show up as rhythmic, repetitive jolts that come every few seconds, sometimes more than fifteen times per minute.2PubMed. Counting fetal hiccups using a fetal movement acceleration measurement recorder Stretches and startles, by contrast, tend to feel like single strong pushes or sudden jumps.
At 25 weeks, the incidence of general body movements is still relatively high. These broad, whole-body motions tend to decrease over the coming weeks as the baby grows and has less room to maneuver.1Early Human Development. Classification and quantitative aspects of fetal movements during the second half of normal pregnancy Meanwhile, breathing-like movements are increasing and will continue rising until about 32 weeks. Hiccups can vary wildly from session to session; some days your baby hiccups several times an hour, other days barely at all. This variability is itself normal and doesn’t signal a problem.
The quality of those movements also shifts as the brain matures. Researchers looking at fetal movement patterns between 26 and 36 weeks have noted a transition from jerky, irregular motions toward smoother, more coordinated ones. These subtle changes in movement quality reflect the development of neural connections in the brain, including the growth of pathways involved in motor coordination.3PubMed Central. Development of Fetal Movement between 26 and 36-Weeks’ Gestation in Response to Vibro-Acoustic Stimulation At 25 weeks, you’re right at the cusp of this transition, so the movements you feel may still be quite abrupt and erratic.
Why You Only Feel a Fraction of What’s Happening
One of the most important things to understand about fetal movement at this stage is that what you perceive is just a sample of total activity. In an exploratory study comparing what mothers felt against what ultrasound revealed in real time, women perceived only about 36% of the movements the scanner showed.4PubMed. Maternal perception of foetal movement compared with movement detected by real-time ultrasound: an exploratory study That means roughly two out of every three movements went unnoticed.
What made a movement more likely to be felt? Three things stood out: movements that involved more than one body part, movements where the baby contacted the uterine wall, and movements that lasted longer. A brief arm twitch deep inside the uterus is unlikely to register. A sustained kick that pushes against the front of the abdomen is much harder to miss.4PubMed. Maternal perception of foetal movement compared with movement detected by real-time ultrasound: an exploratory study This explains why two people at the same gestational age can have very different impressions of how active their baby is, even if the babies are equally active.
Factors That Change How Much You Feel
Several physical factors influence whether the same amount of fetal activity reaches your awareness. The most well-documented is placental position. If your placenta is at the front of the uterus (anterior placenta), it acts as a cushion between the baby and your abdominal wall. A study of 182 patients reporting decreased fetal movements found that reports of reduced movement were about twice as likely when the placenta was anterior compared to other positions.5European Journal of Obstetrics & Gynecology and Reproductive Biology. Fetal movements; factors affecting their perception An anterior placenta doesn’t mean anything is wrong with the baby; it simply means more of the baby’s kicks land against the placenta rather than directly against your body wall.
Body weight also matters. In that same study, women weighing over 80 kilograms were about 1.8 times more likely to report decreased movements, and those over 90 kilograms about 2.6 times more likely.5European Journal of Obstetrics & Gynecology and Reproductive Biology. Fetal movements; factors affecting their perception The researchers concluded that the sensation of fetal movement arises from pressure against the body wall structures rather than from the uterus itself, which helps explain why anything adding padding between the baby and your skin reduces what you feel. Parity, on the other hand, showed no significant association with perception of decreased movement.
There’s also the matter of what you were told to expect. Mothers’ expectations about how often babies should move vary enormously, from 25 kicks per hour to as few as 3 kicks in 24 hours. Receiving specific information about fetal activity roughly doubled the odds that a mother would have high awareness of her baby’s movements.6PubMed Central. Low maternal awareness of fetal movement is associated with small for gestational age infants In other words, knowing what to pay attention to genuinely changes how much you notice.
Daily Patterns and External Triggers
Babies at 25 weeks haven’t developed strong rest-activity cycles yet. Earlier in the second trimester, spontaneous movement appears randomly distributed throughout the day. As pregnancy progresses, longer quiet periods start to emerge, and movement begins to look more cyclical, with quiet intervals progressively lengthening toward term.7PubMed. The development of ultradian rhythms in the human fetus At 25 weeks you’re likely somewhere in the middle of that transition: you might notice some quiet stretches, but the pattern won’t be as clear or reliable as it will be later.
Fetal activity also follows a rough day-night rhythm even before birth, with higher activity during daytime hours. As gestational age increases, the baby’s preference for nighttime inactivity becomes more pronounced, possibly reflecting early development of circadian rhythms.8bioRxiv. From womb to crib: How fetal activity patterns in utero reveal postnatal sleep behavior Many people report that they notice more movement at night, but this likely says more about maternal awareness (lying still, fewer distractions) than about what the baby is actually doing.
Food intake is another trigger. In a qualitative study, about three-quarters of participants said mealtimes were a period of increased fetal activity, and more than a third specifically described heightened movement before meals or when they were hungry.9PubMed Central. Fetal response to maternal hunger and satiation – novel finding from a qualitative descriptive study of maternal perception of fetal movements Some mothers interpreted those hunger-time movements as the baby “asking for food.” Whether the mechanism is a change in blood sugar, increased gut sounds, or something else isn’t fully settled, but the association between meals and fetal activity is widely reported.
How Kick Counting Works and When It Applies
Most clinical guidelines recommend formal kick counting starting somewhere between 26 and 32 weeks, not at 25 weeks. The reason is practical: before the late second trimester, fetal movement patterns haven’t organized enough for a consistent baseline, and the baby is still small enough that many movements go unfelt. That said, 25 weeks is a reasonable time to start getting familiar with your baby’s general activity patterns so you have a mental baseline by the time formal counting begins.
Even among clinicians, there’s no consensus on exact alarm limits. A survey of obstetric practice in Australia and New Zealand found that the most commonly used threshold was fewer than ten movements in twelve hours, used by about three-quarters of respondents. Only 6% agreed with the internationally recommended definition of fewer than ten movements in two hours.10PubMed. Detection and management of decreased fetal movements in Australia and New Zealand: a survey of obstetric practice The variation in clinical practice reflects genuine uncertainty about which threshold best balances sensitivity against false alarms.
The most practical approach at 25 weeks isn’t to hit a specific number but to start learning your baby’s rhythms. Some babies are consistently active, others have longer rest periods and fewer noticeable movements. Both can be healthy. What matters more, as you approach the third trimester, is whether the pattern you’ve come to recognize changes.
When to Contact Your Provider
At 25 weeks, occasional quiet spells aren’t alarming; the baby’s rest-activity cycles are still disorganized, and your ability to feel smaller movements is limited. But a sustained, noticeable reduction in movement from what has become your baby’s normal pattern deserves a call to your provider, regardless of gestational age.
The clinical concern with decreased fetal movements is that they can sometimes signal a baby in distress. In a retrospective study of 203 patients presenting with decreased movements, about a quarter had a poor perinatal outcome, defined as stillbirth, growth restriction, or preterm delivery. The risk of stillbirth was roughly three times higher among those women compared to the general obstetric population. Two or more presentations with decreased movement, a relevant past obstetric history, or measuring small for dates each increased the odds of a poor outcome.11PubMed. Predicting poor perinatal outcome in women who present with decreased fetal movements
It’s worth noting that clinical tools used after a report of decreased movement, including cardiotocography, Doppler blood-flow studies, and ultrasound, have limited evidence for improving outcomes specifically in this context.12Acta Obstetricia et Gynecologica Scandinavica. Decreased fetal movements: background, assessment, and clinical management That doesn’t mean those tests are useless, but it does mean the evidence base supporting formal protocols for decreased fetal movements is thinner than many people assume. The current approach leans heavily on individual clinical judgment, which is one more reason to build a good relationship with your care team early.
Low maternal awareness of fetal movement has itself been linked to increased risk of having a growth-restricted baby, with one study reporting a roughly sixfold increase in odds of a small-for-gestational-age infant among mothers with low awareness.6PubMed Central. Low maternal awareness of fetal movement is associated with small for gestational age infants The direction of causation is debatable: it could be that low awareness causes delays in seeking care, or that a growth-restricted baby moves less, making awareness harder. Either way, paying attention matters.
Movement in Twin Pregnancies
If you’re carrying twins, the picture shifts. Research comparing twin and singleton pregnancies found that twin fetuses were generally less active than singletons throughout pregnancy, likely because of space constraints. However, twins showed higher breathing-like activity in the third trimester. Within twin pairs, overall activity levels tended to correlate, but the babies didn’t tend to move at the same time as each other, especially after 30 weeks, as individual rest-activity cycles began to emerge.13PubMed. Fetal behavior in normal dichorionic twin pregnancy
For parents of twins, this means you may feel less overall movement per baby than a singleton pregnancy would produce, and it can be nearly impossible to tell which baby is moving. Formal kick counting is trickier in twin pregnancies, and many providers adjust their expectations accordingly.
Does Tracking Movement Increase Anxiety?
A common worry is that paying close attention to fetal movement, especially using formal counting methods, will make pregnancy more stressful. The evidence doesn’t support this. A systematic review and meta-analysis found that women who formally counted fetal movements showed higher levels of maternal-fetal attachment but no increase in anxiety or worry compared to those who didn’t count.14PubMed Central. The effect of formal fetal movement counting on maternal psychological outcomes: A systematic review and meta-analysis In fact, a randomized trial found that women who performed fetal movement counting between 28 and 37 weeks reported less state and trait anxiety at 37 weeks compared to controls.15PubMed. The effect of foetal movement counting on maternal anxiety: A randomised, controlled trial
Earlier research reached a similar conclusion, finding no harmful psychological effects in low-risk women who self-monitored fetal activity, and noting that women were generally willing to do the recording.16PubMed. The psychological effects of counting fetal movements If anything, having structured information about what your baby is doing seems to reduce the ambient anxiety that comes from uncertainty. The catch is that all of these studies focused on low-risk pregnancies; people with previous loss or high-risk conditions may have a different psychological response, and that question has less data behind it.
Maternal Stress and Fetal Activity
The relationship between maternal emotions and fetal movement goes both directions. A study of women in late pregnancy found a strong negative correlation between anxiety scores and the time it took to feel ten movements: mothers with higher anxiety perceived their babies reaching that threshold faster.17PubMed. Maternal anxiety and fetal movement patterns in late pregnancy This doesn’t necessarily mean anxious mothers’ babies are objectively more active. It may instead reflect heightened body awareness during anxious states, or stress hormones like cortisol crossing the placenta and influencing fetal behavior. Either explanation, or both, could contribute. What it means for you at 25 weeks is that how you’re feeling emotionally can color your perception of how much the baby is moving, making it harder to establish a reliable baseline during particularly stressful periods.
Why Fetal Movement Matters for Development
Beyond its role as a reassurance signal, fetal movement serves a direct biological function. Mechanical forces generated by a baby’s kicks and stretches are critical for normal skeletal development. Research has shown that when fetal movement is reduced or restricted in utero, the consequences include joint dysplasia, joint contractures, and thin, under-mineralized bones.18PubMed Central. The importance of foetal movement for co-ordinated cartilage and bone development in utero: clinical consequences and potential for therapy The stresses and strains generated by limb movements act as biomechanical signals that help guide bone growth, joint shaping, and the expression of genes involved in skeletal formation.19PubMed Central. Stresses and strains on the human fetal skeleton during development
This means the kicks you feel at 25 weeks aren’t just signs that everything is okay; they’re actively building your baby’s body. Conditions that severely restrict fetal movement, such as certain neuromuscular disorders or severe oligohydramnios, can have lasting orthopedic consequences. For the vast majority of pregnancies, though, the baby’s spontaneous activity takes care of these developmental needs without any intervention.
Fetal Movement and Infant Temperament
One of the more intriguing lines of research connects fetal movement to behavior after birth. A study tracking 52 healthy pregnancies measured fetal motor activity at 24, 30, and 36 weeks, then followed the children through age two. The relationships between prenatal movement and neonatal behavior were inconsistent and small. But by one and two years of age, clearer patterns emerged. Higher fetal activity at 36 weeks was positively associated with observed activity levels in one-year-old boys, though the relationship was reversed for girls. More consistently, fetal movement was negatively predictive of distress to limitations at one year and behavioral inhibition at two years, accounting for a substantial portion of the variation in those measures.20PubMed. What does fetal movement predict about behavior during the first two years of life?
In plain terms, babies who moved more before birth tended to be less easily frustrated and less behaviorally inhibited as toddlers. The researchers noted that fetal motor activity is highly variable from moment to moment, which makes it a shaky predictor of short-term neonatal outcomes but a surprisingly useful one for temperament traits that emerge over the first couple of years. None of this means you should try to interpret your 25-week baby’s personality from the kick count. But it does suggest that the activity you’re feeling reflects emerging nervous system traits that persist well beyond delivery.
