Counting baby kicks
A simple daily habit that lets you spot meaningful changes in your baby's movement — and one of the most useful things you can do in the third trimester.

What kick counts are, and why they matter
A kick count is a brief, structured check of your baby's movements — typically counting how long it takes to feel 10 distinct movements. The point isn't a magic number; it's establishing what's normal for your specific baby, so you can notice if something changes.
Babies have individual movement patterns. One baby might be a kicker who delivers strong distinct jabs; another might be a roller who shifts and stretches in long slow motions. Both are normal. Once you know your baby's pattern, a sustained departure from it — particularly significantly less movement over hours — is what should prompt a call.
Research supports kick-count monitoring in the third trimester as a way to detect decreased fetal movement, which can be an early signal of issues with placental function or fetal wellbeing. Most stillbirths are preceded by a period of decreased movement; catching it early and getting evaluated promptly can make a difference.
When to start kick counts
Most providers recommend starting around week 28 — the start of the third trimester. By that point, movement patterns are established and the baby is large enough that movements are usually clearly perceptible.
If you have a higher-risk pregnancy (diabetes, hypertension, multiple gestation, history of stillbirth, growth restriction), your provider may recommend starting earlier or doing more structured tracking.
Some people start informally noticing movement patterns as early as 22–24 weeks, when first-time parents typically first feel definitive kicks. Formal counting becomes valuable when patterns are reliable enough to detect change.
How to do a kick count
Pick a time of day when your baby is usually active. For most people that's after a meal, in the evening, or after some movement (which often settles the baby into action).
Lie on your side (left side is often most comfortable in the third trimester) or recline in a comfortable position. Set a timer or note the start time.
Count distinct movements — kicks, rolls, jabs, stretches. Each is one count. Hiccups don't count (they're rhythmic and not muscle-driven by the baby's choice). Most babies reach 10 movements within 30 minutes to 2 hours.
Once you've counted 10 movements, you're done. Note how long it took. Over a few days you'll see what's typical for your baby — usually a consistent range.
When to call your provider
Call your provider if it takes substantially longer than usual to reach 10 movements, if you don't reach 10 movements within 2 hours, or if your baby's pattern has changed noticeably over several hours. Don't wait until the next day.
Other reasons to call promptly: any vaginal bleeding, leaking fluid that might be amniotic fluid, severe headaches, vision changes, sudden swelling in your face or hands, or pain that doesn't go away with rest. Any one of these alongside decreased movement is more urgent.
Providers and labor-and-delivery units take decreased-movement calls seriously. You won't be a burden. They'd much rather you call and have everything be fine than miss a problem that needed evaluation.
What evaluation usually looks like
If you call about decreased movement, your provider will typically have you come in for a non-stress test (NST) — a 20–40 minute monitoring session with two belts on your bump that track baby's heart rate and any contractions. It's painless and non-invasive.
An NST that looks normal is reassuring. If anything is unclear, a biophysical profile (BPP) ultrasound may be done — that adds a brief look at amniotic fluid level, breathing movements, and overall tone. Together they give a thorough picture of fetal wellbeing.
Many decreased-movement calls turn out to be normal — the baby was just having a quieter period. Getting checked is still the right call.
