When to Start Counting Kicks (and Why It's Around 28 Weeks)

Most parents should start paying close attention to their baby’s movements at around 28 weeks — the start of the third trimester. That’s the point where movements become strong, frequent, and regular enough that you can actually learn your baby’s normal pattern and notice if it changes. If your provider has told you your pregnancy is higher risk, they may ask you to start earlier; their advice always comes first.

Before 28 weeks, your baby is certainly moving, but the movements are still too faint and scattered to track in any useful way — a quiet afternoon at 22 weeks tells you almost nothing. This page explains why 28 weeks is the usual starting line, who starts sooner, and how to begin.

The short version

Start around 28 weeks — the beginning of the third trimester.
Start earlier only if your provider asks — usually for higher-risk pregnancies.
Why 28 weeks: movements are now strong and patterned enough to track reliably.
First flutters (quickening) ≠ counting. Quickening around 18–22 weeks is a different milestone.
The goal is familiarity — learning your baby’s normal so a clear change stands out.
It’s never too late to begin, even at 36 weeks or later.

Why 28 weeks?

By 28 weeks, your baby is big enough and developed enough that their movements settle into a pattern you can recognise. You’ll start to notice that they’re livelier at certain times of day, quieter at others, and you’ll get a feel for their usual amount and style of movement. That recognisable rhythm is the whole foundation of kick counting — because you can only notice a change once you know what normal feels like.

The American College of Obstetricians and Gynecologists (ACOG) and the American Pregnancy Association both point to the third trimester as the window where movement monitoring becomes meaningful. Earlier than that, movements are real but inconsistent: your baby is small, has plenty of room, and spends a lot of time in positions where you simply don’t feel much. A quiet spell at 24 weeks is usually just that — a quiet spell.

So 28 weeks isn’t a hard biological switch; it’s the practical point where counting starts to tell you something. For the method itself, see our guide on how to count baby kicks.

Who should start before 28 weeks?

Some parents are asked to start sooner. If your provider has flagged any of the following, they may want you watching movements earlier or more formally:

A pregnancy considered higher risk (for example, certain medical conditions, or concerns about your baby’s growth).
A previous pregnancy with reduced movements or a difficult outcome.
Twins or more, or other situations your team is monitoring closely.

The rule here is simple: your provider’s instructions beat any general guideline. If they’ve given you a specific week to start, a specific method, or a threshold to call about, follow theirs. The 28-week guidance is for an uncomplicated pregnancy; your team tailors it to you.

Isn’t the first kick the start? Quickening vs. counting

This trips a lot of people up, so it’s worth separating two different milestones.

Quickening is the first time you feel your baby move — those early flutters, bubbles, or “popcorn” sensations. For a first pregnancy it usually arrives somewhere around 18 to 22 weeks; in later pregnancies you often feel it earlier because you know what to look for. Quickening is a genuine, lovely moment, and it tells you your baby is on the move.

But quickening is not the same as kick counting. Those early movements are too faint and far too irregular to track — you might feel a flurry one day and nothing the next, and neither means anything is wrong. Structured counting waits for the third trimester, when movements are strong and patterned enough that a clear drop would actually stand out. Feeling early kicks is about connection; counting later is about a measurable baseline.

We map out how movement changes as pregnancy progresses in our week-by-week guide to baby movements.

How to start once you reach 28 weeks

Getting going is low-effort. The aim of the first week or two isn’t to catch a problem — it’s simply to learn your baby’s normal:

Pick a time your baby is usually active — after a meal, after something cold to drink, or in the evening when you settle down.
Lie on your left side somewhere quiet so you can feel each movement.
Notice the rhythm: roughly when your baby gets going, how long it takes to feel ten movements, what the movements feel like.
Don’t panic over variation. Babies have sleep cycles of 20 to 40 minutes; a slow start often just means a nap.

After a handful of sessions you’ll have a working sense of your baby’s pattern. From then on, you’re not chasing a number — you’re watching for a clear, lasting departure from that pattern. A common target many parents use is ten movements within two hours; we explain that in what “10 kicks in 2 hours” means.

What if I haven’t started and I’m already well into the third trimester?

Start now. There is no deadline you’ve missed. Whether you’re 30, 34, or 38 weeks, your baby’s movements remain one of the clearest, simplest signs of their wellbeing — and you’ll learn their normal within just a few days of paying attention. Late is infinitely better than never, because the whole value of counting lives in the last weeks, when it matters most.

When to call your provider

Once you’re counting, contact your midwife or doctor the same day if:

You don’t feel ten movements in two hours during a count.
Movements are clearly fewer or weaker than usual for your baby.
You notice a sudden change from the pattern you’ve come to expect.

And before you’ve even established a pattern — at any stage in the third trimester — if you simply feel that your baby is moving less than they were, call. You don’t need a chart or an app to give you permission; your instinct is the first instrument. Maternity units would always rather check a baby who turns out to be fine.

Common questions

Can I start counting kicks before 28 weeks? You can pay attention any time, but formal counting before about 28 weeks is rarely useful because movements aren’t yet strong or regular enough to track reliably — quiet spells are normal and don’t mean much earlier on. If your provider has flagged your pregnancy as higher risk, they may ask you to start earlier; follow their guidance over any general rule.

Is it too late to start counting at 36 weeks? Not at all. Starting at 36 weeks, or even later, is genuinely worthwhile — your baby’s movements remain an important sign of wellbeing right up to and through labour. You’ll learn your baby’s normal pattern within a few days. It’s never too late to begin paying closer attention.

When did I feel my first movements, and is that different from counting? Most first-time parents feel the first flutters — often called quickening — somewhere around 18 to 22 weeks, and earlier in later pregnancies. That’s a lovely milestone, but it’s separate from kick counting. Early flutters are too faint and irregular to track; structured counting waits until the third trimester when movements are strong and patterned.

Do I need to count every day once I start? Not necessarily. ACOG doesn’t prescribe one schedule for everyone. The goal is to become familiar enough with your baby’s normal that you’d notice a real change — counting on most days in the third trimester is a simple way to build that familiarity. Some parents count daily; others check in a few times a week. Consistency helps more than rigid perfection.

Does a posterior placenta change when I’ll feel enough to count? It can. With an anterior placenta — one sitting on the front wall of your uterus — the cushion can mute movements, so you may feel less, especially earlier on. That doesn’t mean your baby moves less; it means you feel less of it. You’ll still learn your own normal once you reach the third trimester, and your provider can reassure you about your specific placenta position.
