Beginning around 20 weeks, you should feel the baby's movements.  By 26-28 weeks, you should be aware of some movement every day.  Lack of movement could be a sign of a problem.  Therefore, it is a good idea to pay close attention to whether or not the movement pattern has changed.  "Fetal kick counts" are performed by monitoring the baby's movements for two hours after you have had a meal, and are able to relax and focus on what you feel.  There should be at least one movement within two hours.  If not, eat something sweet, lie on your left side, and monitor closely for one additional hour.  If no movement is noted, go to Labor and Delivery.
