The cervix will open at the beginning of labor. Then, at regular intervals, the uterine muscles start to contract. In between each subsequent contraction, the uterus will relax. Before labor starts and throughout the early stages of labor, the baby will continue to move.  The movement pattern, though, might alter. For example, the unborn child might wiggle or shuffle instead of kicking the womb.  The sensation of the baby's movement gives reassurance that the child is healthy. On the other hand, the reduced baby movement could indicate that the infant is having problems. In these situations, speaking with a doctor is helpful.
