After 18 to 20 weeks, you will notice that your baby moves and kicks
more at certain times of the day. For example, when you are active, you may
notice less kicking than when you are resting quietly. At your prenatal visits,
your health professional will ask you whether the baby is active. Your sense of
your baby's movement is a good measure of how well the baby is doing in the
womb.1
In the last trimester of your pregnancy, your health professional may
advise you to keep track of the baby's movement every day. A common method of
checking your baby's movement is to see how much time it takes to feel 10
movements. Ten movements (such as kicks, flutters, or rolls) in 1 hour or less
are considered normal, but do not panic if you do not feel 10 movements. Less
activity may simply mean the baby is sleeping.
If you are unable to feel 10 movements over an hour, continue
counting for a second hour. If you count fewer than 10 movements over a 2-hour
period, call your doctor immediately.
