Fetal movement: when it starts and when to worry
If you've heard “count your baby's movements, you need at least 10 in 2 hours,” good news: that rule has been outdated for a while, and even the more recent version that replaced it has just been revised again. Here's what you really need to know about when movement starts and, above all, what to do if you notice a change.
When movement actually starts (and why it varies from person to person)
Women who've already had a pregnancy before usually feel the first movements between weeks 16 and 18; for a first pregnancy, the typical window is between 18 and 25. The difference has nothing to do with how “attentive” you are: someone who's already been through a pregnancy already knows how to tell fetal movement apart from gut rumbles or other internal sensations, while in a first pregnancy it takes more time to learn to recognise it.
In the early weeks the movements are light, almost imperceptible, often described as a “flutter” or small bubbles. They gradually become clearer and more recognisable over the course of the second trimester.
“Count 10 movements in 2 hours”: why this rule is outdated
For years the advice was to count fetal movements until reaching a fixed threshold (typically 10 in 2 hours) as a self-monitoring method. The most recent clinical guidelines, starting with the RCOG Green-top Guideline No. 57 on reduced fetal movements, state that there's no evidence to support formal counting as a way to decide whether to worry or not.
The problem with counting is that it creates a false sense of security: if the baby moves less but still “enough to reach 10,” the count says everything is fine, even when something has actually changed and deserves attention.
What the most recent guidance (2025-2026) actually says
In 2025, an update led by organisations specialising in preventing perinatal mortality (Sands, together with Tommy's, the NHS, and others) went a step further: it dropped even the more recent language based on “pay attention to the pattern” or “to any changes,” because it was still considered too vague, a project collecting testimonies from bereaved parents showed that phrases like “pattern” were interpreted too differently from person to person.
The current message is deliberately simple and direct: call your midwifery unit or maternity ward straight away if the baby moves less, if the movements are weaker, or if they've stopped, with no need to count anything, no need to be 100% sure, no need to wait to “see if it passes.”
What to actually do if you notice a change
- Call, don't wait. That holds at night too, even if you feel like you're overreacting: in the great majority of cases the check-up ends reassuringly, but it's still the right call to make.
- Don't try to “stimulate” the baby yourself with sugar, cold drinks, or pressing on your belly to see if there's a reaction, before calling: it's not a reliable method and only risks wasting time.
- Don't wait for the next scheduled appointment. A change in movement is one of the few situations in pregnancy where “the sooner you call, the better” applies without exception.
Is it true that movement decreases towards the end of pregnancy?
As you get closer to your due date, the space inside the uterus shrinks, and movements can feel different, less sweeping, more like pushes or rolls than sharp kicks. But the baby keeps moving regularly right up to labour: there's no normal phase where movements stop or drop off sharply. A genuine perceived reduction, even in the final week, should always be reported with the same urgency as in earlier weeks.
The single most important takeaway from this article
If there's one thing to take away: there is no right number to hit. You don't need to reach 10 movements, you don't need to clear a threshold, you don't need to wait to figure out if it's “just a quiet day.” Just doubting that something has changed from usual is reason enough to call, and it's always the right choice.
In summary
The first movements are usually felt between weeks 16 and 25, earlier for those who've already had a pregnancy before. The old “count 10 movements in 2 hours” is no longer the correct clinical recommendation: today you call your midwifery unit straight away if the baby moves less, more weakly, or has stopped, with no need to count or wait.
Frequently asked questions
When do you start to feel the baby move?
Usually between weeks 16 and 18 if you've already had a pregnancy before, and between weeks 18 and 25 for a first pregnancy, because you haven't yet learned to tell fetal movement apart from other internal sensations.
Is it true you're supposed to count movements during the day?
No, not any more. The old “count 10 movements in 2 hours” rule is outdated: the most recent guidelines (RCOG, Sands, Tommy's) say not to count, and to contact your midwifery unit straight away if the baby moves less, more weakly, or has stopped, regardless of any number.
What should I do if I feel the baby moving less?
Contact your midwifery unit or your OB-GYN straight away, even at night, even if you're not 100% sure. There's no need to wait, no threshold to hit, no need to “see if it passes on its own”: it's a call you make regardless, and in the great majority of cases it ends with a reassuring check-up.
Do I need to be sure before calling the midwife?
No. The most up-to-date guidelines recommend calling even if you're only unsure, without waiting for certainty. An extra check-up has no downside; a delay can.
Do movements normally decrease towards the end of pregnancy?
Space gets tighter and movements can feel different (less sweeping, more “squeezed”), but the baby keeps moving regularly right up to labour. A genuine perceived reduction should always be reported, even in the final weeks.
What does the most recent guidance on fetal movement say?
The 2025 update (Sands, Tommy's, the NHS, and other specialist organisations) dropped even the vaguer “pay attention to the pattern” language, because it was considered ambiguous, replacing it with a direct message: call if the baby moves less, more weakly, or has stopped.
