If your baby is moving less than usual, call your midwife or doctor tonight, even if it is late, even if you are not sure. That is the whole answer, and the rest of this post exists because I once spent an evening on a sofa trying very hard not to arrive at it.
What kept me on the sofa was a number. Somewhere online there is a version of ten movements in two hours waiting for you, and it feels like a test you can pass without picking up the phone. I went looking for it in my first pregnancy. The bodies that would actually know refuse to give one, and once you understand why they refuse, the refusal becomes the most useful thing anyone tells you about movement.
The number you are looking for does not exist
Here is what that evening looked like. It was my first pregnancy, a quiet afternoon that turned into a quiet dinner, and by the time I sat down I could not remember her last kick. So I did the thing. Hand on my belly, feet up, phone in the other hand, counting. I got to four and stalled, and instead of calling anyone I started searching for how many would mean she was fine.
The refusal is unanimous. The NHS puts it flatly: there is no set number of movements you should feel each day, every baby is different, and you do not need to count. The Royal College of Obstetricians and Gynaecologists says the same thing from the clinical side, that there is no specific number of movements considered normal.
At first this feels like being abandoned. You came for a pass mark and they will not set one. But the reason they will not is the actual answer. Your baby has a pattern, hers and nobody else’s, and you are the only person alive who knows it. “Less than her usual” is the whole test, and there is no number that overrides it.
Which means the hour I spent counting toward a threshold from a forum was me grading the wrong exam. The data I needed was already in my head. I knew her usual. Her usual was the reason I was worried enough to be counting at all.
If you are early enough that there is no pattern yet, the timeline belongs to the NHS: first movements arrive between 16 and 24 weeks, often after 20 in a first pregnancy, and if you have felt nothing by 24 weeks, that on its own is a reason to tell your midwife.
What counting is actually for
None of this makes counting fake. It makes counting a prescription, and prescriptions come from someone who has actually seen you.
Kick counts, in the version that exists in the guidance rather than the one that circulates online, are a home test your health care professional may ask for after you report feeling less movement. ACOG is careful in exactly the place the internet is careless: there are different ways kick counts can be done, and your health care professional will tell you how often to do them and when to call. The method and the phone number come attached. That is the entire difference between a kick count and what I was doing on the sofa.
The self-assigned midnight version has neither. It has a threshold from a stranger and no one waiting on the result.
Even the chart, the printed grid people once filled in daily, is not a blanket recommendation. There is not enough evidence to recommend routine movement charts, in the RCOG’s reading. A count is something you are handed, for a stretch, with instructions. It is not a subscription.
Reduced movement also sits on ACOG’s list of reasons for the bigger tests, the ones done in a clinic from around 32 to 34 weeks, alongside things like growth problems and high blood pressure. I find that list clarifying rather than frightening. It means “she is moving less” is a sentence the system takes seriously. One more reason not to sit on it alone.
Ninety minutes is the longest nap
The most useful number I have ever been given about movement is not a kick count at all. It is a nap length.
Babies sleep in the womb, in cycles the RCOG puts at mostly 20 to 40 minutes and rarely longer than 90. That gives a quiet stretch a shape. Half an hour of stillness is an ordinary nap. Two silent hours is not a nap, and “she is probably just asleep” quietly stops being available as a reason to wait.
Your own day blurs the picture too. You notice less when you are up and moving, which is why this worry so often lands in the evening, at the exact hour everything finally goes still. That was my evening. She had likely been moving all afternoon while I was on my feet and busy. Some of the stillness I was counting was mine.
The body has its own muffles as well. A placenta sitting at the front of the uterus can cushion movements so you feel them less, and the RCOG also lists strong pain relief, sedatives, alcohol and smoking as things that genuinely slow a baby down. None of those change what a change in pattern means. They are reasons you might miss her usual, not reasons her usual stopped.
Then there is the myth, the one somebody kind will offer you near the end: that babies slow down late in pregnancy because they run out of room. The RCOG’s numbers say otherwise, with movements increasing until 32 weeks and then holding steady, and the NHS goes further still, that you should feel your baby move right up to and during labor. A baby who has gone quiet near the end is not out of room. She is out of pattern, and that is the phone call again.
The tricks that feel like checking
Before I called anyone that night, I ran the full folk protocol. A glass of cold water. Orange juice, because a forum said sugar wakes them up. Lying on my left side. Pressing gently on one side of my belly and waiting, like knocking on a door.
Here is what I can tell you about those tricks. The three pages I trust on this subject, from ACOG, the NHS and the RCOG, are open in front of me as I write, and the cold water and the juice appear on none of them. Not as advice, not even as a warning. The whole ritual lives somewhere outside the guidance entirely.
The doppler deserves more than absence. On this the NHS is explicit: do not use a home doppler to try to check the heartbeat yourself, it is not a reliable way to check your baby’s health, and even if you hear a heartbeat, this does not mean your baby is well. The RCOG’s version is shorter, do not rely on any home kit for listening to your baby’s heartbeat.
What the water, the juice, the poking and the doppler all have in common is that they produce something that feels like an answer and is not one. A kick after orange juice does not tell you her pattern is back. A heartbeat through a speaker tells you even less. Only two things can actually read a change in movement, the pattern in your head and the people at the end of the phone, and only one of those can order a monitor.
The call you are putting off
I did make the call that night, eventually, and what I remember is how unremarkable it was on their end. I had rehearsed a small apology for wasting their time. Nobody needed it. The whole conversation was shorter than the counting had been.
The NHS instruction has no soft edges, and it is worth reading slowly. Call your midwife or maternity unit immediately if your baby is moving less than usual, if you cannot feel your baby moving anymore, or if there is a change to your baby’s usual pattern of movements. Do not wait until the next day. Call immediately, even if it is the middle of the night.
And if this is not your first time calling, the guidance already thought of you. Never go to sleep ignoring a reduction or change in your baby’s movements, the RCOG says, and you should never hesitate to contact your midwife or maternity unit no matter how many times this happens. The tenth call is as legitimate as the first. Movement is one of the two places in pregnancy where I have learned the phone beats the internet every single time. When vomiting crosses its own lines is the other.
The baby I was counting that night is three now. She is the same girl who was delivering crackers to my nightstand earlier in this pregnancy. This time around, the only thing I have kept from that sofa is the rule I should have started with: usual is the test, a change in it is a call, and the call happens the same night.
The short version
- Learn your baby’s usual on an ordinary day, not in the middle of a worrying one. That pattern is the thing you will be measuring against, and nobody else has a copy.
- Short quiet stretches are naps. A long silent evening is a change.
- If tonight feels like less than usual, the phone comes before the water, the juice and the counting.
- The middle of the night counts. So does the tenth call. Nobody on the other end thinks you are wasting anything.
- The doppler in the drawer answers a different question than the one you are asking. Leave it there.

A note on this post. Written and edited by the NewBloom editorial team. NewBloom is not written by doctors, nurses or midwives, and nothing here is medical advice. We read the current guidance from bodies like ACOG, the CDC and the NHS and write down what it says, with every claim traced to its source and named in the sentence where it appears. General guidance is not the same as an answer about your own body. Your doctor, midwife or health visitor can examine you and we cannot, so anything here that raises a question about your own pregnancy is a reason to ask them.
