Is it normal for my baby to move only at night?

Yes. Many babies have naturally active nighttime phases. What matters is that your baby maintains a consistent pattern.

Should I count kicks during the day?

Use your baby’s active time rather than a specific clock time. Some babies show more movement at night.

Does movement reduce as the baby grows?

No. Movement may feel different, but it should not reduce.

Why Some Babies Move Less During the Day and More at Night

You spend your day walking, working, bending, and moving through your routine. Your baby feels these movements constantly. The gentle rocking created by your steps often lulls your baby into quieter states, much like a cradle that keeps a newborn calm. When you finally lie down at night, everything becomes still. That stillness allows your baby to move freely without the rhythmic sway of your body. It is usually at this moment that you feel the sudden thumps, flutters, rolls, or kicks that were muted earlier.

This pattern often comes as a surprise to mothers because it feels backwards. You may assume your baby would mirror your activity level or rest when you rest. But foetal behaviour follows its own internal rhythm, shaped by neurological development, sleep cycles, and sensory experiences inside the womb. Research shows that foetuses have active and quiet sleep phases, and these cycles continue even when your daily routine changes. That is why your baby’s night-time energy usually reflects their internal schedule, not your tiredness.

When you understand what drives this pattern, those late-night kicks feel less confusing and more like a healthy sign of growth.

How Babies Develop Their Own Sleep–Wake Cycles

Your baby does not follow a day-and-night schedule the way you do, but they do develop patterns.

A developing nervous system: As your baby’s brain matures, especially after 24 to 28 weeks, they begin experiencing cycles of:

quiet sleep
active sleep
wake-like activity

Studies in foetal behaviour show that active sleep is the phase associated with most movements.

They do not sense light the way you do: Although light can pass through your abdomen, it is diffused. Babies cannot distinguish daytime brightness from nighttime darkness the way adults do. Their rhythm is therefore guided more by your movement, their nervous system, and hormonal cues than by external light.

Melatonin transfer from you: Your body produces melatonin at night. This hormone crosses the placenta and can influence foetal activity, especially in the final trimester. Some research suggests melatonin may increase foetal movement during your nighttime hours.

Active sleep peaks at night: It's when your baby kicks, stretches, rolls, and shifts. This phase naturally peaks in the evening hours for many babies, regardless of your routine.

Your baby’s sleep–wake cycle is not a reflection of your lifestyle. It is simply how foetuses develop, and it continues after birth when newborns often remain awake at night and sleep deeply during the day.

Why Babies Move Less During the Day

Even though your baby is growing and kicking continuously, you may feel very little during your busy hours. Several factors shape this.

Your movement rocks the baby to sleep: When you walk, drive, or even stand, your baby experiences a smooth rocking sensation. This can be calming and may encourage a quieter state.

Your focus is elsewhere: Daytime distractions reduce your awareness of subtle movements. At night, when everything is quiet, you detect smaller movements more easily.

Uterine compression changes with posture: When upright, your abdominal muscles and uterus offer more resistance. Movement is often dampened and less perceptible.

The placenta’s position affects perception: If you have an anterior placenta, movements during the day may feel muted. At night, your stillness may make those same movements more noticeable.

Your baby may genuinely be resting: Foetuses spend long periods asleep, up to 90 percent of the time. Some of these naps coincide with your active hours.

These daytime patterns are typical and do not mean your baby is less healthy or less active overall.

Why Babies Move More at Night

Once you lie down, shift your posture, and relax your muscles, the environment inside your womb changes sharply.

You are still: Without your body’s rhythmic motion, your

baby has more opportunity to stretch and reposition.

Your awareness increases: Even small kicks feel stronger when there is no competing noise or distraction.

Better uterine space distribution: Side-lying positions give your baby more room to flex and move, especially in late pregnancy.

Maternal blood flow shifts: Blood flow to the uterus increases when you lie down, and some studies suggest this may enhance fetal activity.

Melatonin influence: Nighttime hormonal changes can stimulate fetal movement.

This pattern does not mean your baby prefers to wake you up. It means you are finally quiet enough to notice the movement they were making all along.

What Normal Foetal Movement Really Looks Like

Foetal activity varies throughout pregnancy, but certain principles remain consistent.

Movement should have a recognisable pattern: By the third trimester, you generally know when your baby is most active. This does not always match another mother’s experience.

There is no fixed number of movements per hour: WHO and NHS guidelines emphasise that a change in your baby’s usual pattern matters more than hitting a specific number.

Movements continue until birth: Babies do not run out of space late in pregnancy. Movements may feel different, but should not decrease.

Stable patterns are reassuring: If your baby is always more active at night and quieter during the day, that pattern alone is normal.

Normal does not mean identical across pregnancies. You may have one pregnancy with strong night kicks and another with balanced daytime movement.

When Less Movement Is NOT Normal

While day-night differences are common, any noticeable drop in your baby’s overall movement needs attention.

Red flags
Your baby is less active than usual during their typical active window
You cannot feel movements during a time when you normally do
You feel fewer strong kicks, rolls, or jabs
Your baby’s movement suddenly becomes weak or faint
You notice a change and cannot reassure yourself after lying on your side

NHS guidance advises contacting your healthcare provider immediately if movements reduce, regardless of the time of day.

Do not wait until morning: This is one area where prompt evaluation matters. Reduced movement can be linked to fetal growth issues or placental concerns. An NST or ultrasound often provides immediate clarity.

What Affects Movement Perception

Sometimes the baby is moving, but you cannot feel it clearly. These factors play a major role.

Placenta location: An anterior placenta can cushion kicks, especially early on.

Amniotic fluid levels: Higher fluid volumes may soften movement sensations.

Your body weight: Movements may feel subtle, but they are still happening.

Baby’s position: If your baby is facing your spine, kicks aim backwards.

Gestational age: Before 24–26 weeks, movement is irregular and easy to miss.

Awareness does not always equal movement. This is why pattern recognition is more valuable than comparing yourself to others.

How to Track Movement Safely

Tracking does not mean counting aggressively. It means getting familiar with your baby’s usual rhythm.

Choose a consistent time: Evenings often work best because your baby is alert.

Lie on your left side: This improves blood flow to your uterus.

Observe for 1 hour: You should feel movements during your baby’s typical active window.

Do not wait long if patterns shift: Hospitals prefer early evaluation rather than delayed assessment.

Kick counting apps may help some mothers, but paying attention to your baby’s usual pattern is more reliable.

Your baby’s habit of moving less during the day and more at night reflects their internal rhythms, developmental stage, and how your body supports them as you go through the day. This contrast can feel confusing, but it is almost always normal. Paying attention to your baby’s unique pattern helps you feel confident and connected, and lets you know when to seek help if something changes.
