My little one is being quiet too.. But it does depend on the position of the baby as Em said it may just have more room in some positions than it does in others. The position of the placenta and the amount of fluid present will mask the feelings too. Also if you are a larger lady you may not feel kicks as much. The most active time is around 9pm at night so relax and try to concentrate then! If you are running around busy all day you may just miss them!! Good excuse to put your feet up I say!!
