Light-headedness can happen when there are changes in the circulatory system. Those pregnancy hormones make the body a little slower at adjusting to changes in position. During the later part of pregnancy, the pressure of an enlarged uterus slows circulation in the legs.

To help prevent light-headedness:

• Take things slow. Avoid sudden changes in position.
• Get regular exercise.
• Practice deep breathing. It helps to increase the amount of oxygen in the bloodstream. Parents can do this together. It's very relaxing.
• Avoid hot environments and keep the space you're in cooler.
• Try not to skip meals.
• Move your legs frequently throughout the day, especially when you are sitting.
