About babyâs movements
An active baby is usually a healthy baby. You
will feel your baby stretch, kick, roll and turn
every day. Some babies are more active than
others. All babies have periods of sleep during
which they are not as active. You will get to
know your babyâs pattern of movements and
when your baby is most active.
You should feel your babyâs movements
throughout the day, each day from 28 weeks of
pregnancy until the baby is born.
When during my pregnancy should I count
my babyâs movements?
Your health care provider may ask you
to count your babyâs movements once
every day.
If you think there is a decrease in your
babyâs movements this is an important sign that
your baby may not be well. Count your babyâs
movements to be sure that you feel at least 6
movements in 2 hours.

How do I count my babyâs movements?
⢠Get into a comfortable position â lying on
your side or sitting. Place one or both of your
hands on your abdomen.
⢠Count each time that you feel your baby
move. If you feel many movements all at
once, count each movement that you feel.
⢠Write down the date and the time that you
start counting on the fetal movement chart.
⢠Make a mark on the chart each time your baby
moves.
⢠Stop counting when you have counted 6
movements.
⢠Write down the time you stopped counting.
⢠Do not count for more than 2 hours
What if I donât feel 6 movements in 2 hours?
Count your babyâs movements once a day. You
should feel 6 or more movements in 2 hours.
If you count fewer than 6 movements in 2 hours
do not wait. Go to the hospital or birthing unit.
Your babyâs heart rate and movements will be
checked using a fetal monitor. This is called a
non-stress test or NST.
If you live too far from a hospital or birthing
unit, immediately contact your health care
provider for advice.
