Noticing that your baby is moving less than usual is one of the most anxiety-inducing experiences in pregnancy. Here's what the evidence actually says — and what you should do about it.
The previous advice to count kicks — aiming for a specific number per day — is no longer recommended by the RCOG (Royal College of Obstetricians and Gynaecologists) or the NHS. Research found that formal kick counting creates more anxiety than it prevents and does not reliably detect problems.
What matters instead is awareness of your individual baby's pattern of movements. Every baby is different. What you're looking for is a change from what's normal for your baby — not whether they've hit a threshold number.
This is one of the most persistently wrong pieces of advice still in circulation — sometimes from healthcare professionals. The claim that babies 'run out of room' and move less in the third trimester is not supported by evidence.
The RCOG guideline is explicit: fetal movement should stay roughly the same from 32 weeks until labour begins, and you should continue to feel your baby move right up to and during labour. The character of movement may change as the baby grows — large kicks may become rolling pressure — but frequency should remain consistent. A noticeable decrease is clinically significant information, not a normal part of late pregnancy.
If your placenta is at the front of your uterus (an anterior placenta, identified at your 20-week scan), it acts as a cushion that reduces the intensity of what you feel — particularly before around 28 weeks. This is normal and doesn't affect your baby's wellbeing.
If you have an anterior placenta, it's especially important to be guided by change from your own pattern rather than specific numbers. Crucially, an anterior placenta is not a reason to delay contacting your maternity unit if you're concerned — it simply affects how you perceive movements, not whether they should be monitored.
If you notice a significant reduction in your baby's movements, or movements that feel different from their usual pattern, the guidance is unambiguous: contact your midwife or maternity unit straight away. Not tomorrow. Not at your next appointment. Maternity units are staffed 24 hours a day, 7 days a week for exactly this reason.
Around 70% of women who report reduced fetal movement have a normal outcome. But reduced movement can also be an early sign of a problem that is detectable and manageable if identified promptly. The monitoring — usually a CTG, a 20-minute trace of the baby's heartbeat — is non-invasive. No call about your baby's movements is ever 'too cautious.'
Home dopplers — handheld devices to listen to your baby's heartbeat — are widely used as reassurance. The NHS and RCOG are clear on this: hearing a heartbeat on a home doppler does not mean your baby is well.
A heartbeat can be present even when a baby is in distress. Correctly interpreting a CTG trace requires training. Using a home doppler to reassure yourself about reduced movement delays appropriate assessment. If you're concerned about movement, call your maternity unit — don't reach for the doppler.
