I am nearing the end of my second trimester and I sometimes don't feel my baby move for a while. This scares me. A friend told me she counts her baby's movements. She has assisted at over 1,000 births and is currently teaching in the nurse-midwifery program at the University of Minnesota.
Fetal movement can be quite variable.
Babies in utero have sleep and wake cycles of their own. There are many methods to count fetal movement. Around 28 weeks your care provider will discuss counting fetal movements. Most methods involve counting any fetal flutter or movement for a period of several hours. For example, start counting when you get up in the morning.
