as your baby grows he or she will move less as long as you feel the baby move up to 5 times in a hour you have no need to worry. try laying on you back or relaxing in a bath and watch you may see the baby move. if you are really scaried go see your obgyn.

Let babeblues said, I wouldn't trip. My little girl did the same thing. She was wild for a bit and then she just chilled. I was paniced and thought something was wrong. We went to the doc and it turned out the be nothing. It is always better to air on the side of caution. I refuse to take a chance with my daughters life.
