Sit or lie on your side in a comfortable spot during a time of day when your babies are usually active. That could be after eating or moving around. There are lots of ways to chart movements. The simplest one is to record the amount of time it takes for you to feel 10 movements, such as kicks, rolls, or jabs. You should feel 10 movements in no more than two hours. Write down the time and day in a journal. If you don't feel your babies move about 10 times in two hours, call your doctor.
