While it's important to pay attention to your baby's movements in utero, decreased fetal movement doesn't always mean there's a problem with the pregnancy. Because it's better to err on the side of caution, count your baby's kicks during the time they are usually most active.

When should you worry about reduced fetal movement?

If you reach 10 before the second hour is up, you and baby are good to stop the count. But if you consistently monitor a kick count on a daily basis and then notice a day when the movements drop off, call your doctor.

Do baby kicks get weaker?

Don't panic if you notice weaker kicks after that 30-week mark. At this point, researchers found kicks are reduced to about 3.8 pounds of force as baby begins to run out of room to move around. From 28 weeks on, doctors suggest doing kick counts to keep tabs on baby's normal activity.
