Why does my baby have periods of very frequent fetal movements?

Patient's question:

No

Doctor's answer:

Normal fetal movement is 3 to 5 times per hour. Alternatively, multiply the number of fetal movements measured in 3 hours by 4 to equal the 12-hour fetal movement count, which should be 30 or more. An increase or decrease in fetal movement suggests an abnormal condition in the fetus and requires prompt medical attention.
