I'm worried about my baby's movements, what should I do? Expand If you think your baby’s movements have slowed down or stopped, contact your midwife or maternity unit immediately (it is staffed 24 hours, 7 days a week). Do not put off calling until the next day to see what happens. Do not worry about phoning, it is important for your doctors and midwives to know if your baby’s movements have slowed down or stopped. Do not use any hand-held monitors, dopplers, or phone apps to check your baby’s heartbeat. Even if you detect a heartbeat, this does not mean your baby is well.
