Counting kicks: monitoring fetal movement in pregnancy
Feeling your baby move is one of the most reassuring parts of pregnancy, and staying aware of those movements plays an important role in your baby's safety, particularly in the third trimester. NHS guidance is clear: knowing your baby's own pattern of activity and acting promptly if it changes is one of the most valuable things you can do in the later weeks of pregnancy. This article explains what to expect, what to look out for, and when to seek help without delay.
When you will first feel your baby move
For most pregnant people, fetal movements become noticeable somewhere between 18 and 24 weeks. In a first pregnancy the earliest movements can feel like flutters or bubbles that are easy to miss. In subsequent pregnancies, many people recognise those sensations earlier, sometimes before 18 weeks, because they know what they are looking for. If you reach 24 weeks without having felt any movement, let your midwife know at your next appointment rather than waiting to see if anything changes.
By around 24 to 28 weeks, most babies have settled into a recognisable pattern of activity. From 28 weeks onward you should be actively aware of your baby's usual level of movement. This is not about counting every kick but about building a general sense of what is normal for your baby specifically.
There is no magic number of kicks
One of the most important pieces of guidance from the NHS is that there is no single correct number of movements per day that applies to every baby. Each baby has its own rhythm. Some are more active in the evenings, others move more noticeably after meals or during certain times of day. What matters is not hitting a fixed target but understanding what your individual baby's normal looks like.
Older approaches to kick counting, such as charts that set a goal of ten movements within a certain time window, are no longer recommended. The focus now is on awareness of change rather than reaching a number. If your baby's movements feel different from what you are used to, whether less frequent, weaker, or simply not quite right, that is the signal to act.
Why movement monitoring matters
Fetal movements are a sign that your baby is doing well. A change in the pattern or a noticeable reduction in movement can occasionally indicate that a baby needs attention. The NHS is careful not to cause unnecessary alarm, but the evidence is clear that taking reduced movement seriously and having it checked promptly is important. A reduction in movement is not automatically a sign that something is wrong, but it is always worth having assessed rather than waiting to see what happens.
Kicks Count, the UK charity dedicated to supporting parents with fetal movement information, reinforces this message: contacting your maternity unit when you notice a change is the right response, regardless of what time of day or night it is.
Do not rely on a home Doppler device
Home Doppler devices, the handheld equipment that lets you listen to your baby's heartbeat at home, can feel reassuring but are not a reliable way to assess your baby's wellbeing. Detecting a heartbeat with a home Doppler does not mean everything is fine. It is possible to find a heartbeat even when a baby is in distress, because movement patterns and heart rate variability over time tell a far more complete story than a single brief listen. NHS guidance is explicit on this point: if you are concerned about your baby's movements, the right action is to contact your maternity unit, not to reach for a home device.
When to contact your maternity unit
If you notice that your baby is moving less than usual, or if the pattern of movement has changed in a way that does not feel normal for your baby, contact your maternity unit straight away. This applies at any time, including overnight and at weekends. You should not wait until the next morning, and you should not wait to see if movements pick up on their own. The NHS is unambiguous on this: act on the change when you notice it.
When you call, the team will likely ask you to come in so they can carry out a cardiotocograph, known as a CTG. A CTG records the baby's heartbeat and its pattern of movement over a period of time, giving the clinical team the information they need to assess how the baby is doing. This is a straightforward and non-invasive check.
Please do not feel that you will be wasting anyone's time. Maternity units expect and welcome these calls. Contacting them is exactly what you are supposed to do, and the staff will never make you feel that your concern was not worth raising.
Frequently asked questions
When should I start feeling my baby move?
Most people feel movements for the first time between 18 and 24 weeks. In a first pregnancy it often feels like flutters. In subsequent pregnancies you may notice movements earlier. If you have not felt movements by 24 weeks, mention this to your midwife.
How many kicks should I feel per day?
There is no specific number that is right for every baby. What matters is becoming familiar with your own baby's pattern of movement and noticing if it changes. Kick counting charts that aim for a fixed number are no longer recommended by NHS guidance.
What should I do if my baby is moving less than usual?
Contact your maternity unit immediately, any time of day or night. Do not wait to see if movement picks up, and do not use a home Doppler device. The midwives can check your baby's wellbeing with a CTG monitor and will always be glad you called.
Is it normal for movements to change in the third trimester?
The type and character of movements may change as the baby grows and has less room, but the frequency of movements should not consistently decrease. If your baby seems less active than usual for your personal pattern, always contact the maternity unit rather than assuming it is because there is less space.
