1. Practice good posture

As your baby grows, your center of gravity shifts forward. You might lean back to keep yourself from tipping forward. But leaning back can strain the muscles in your lower back. Straining muscles can play a role in back pain during pregnancy.

Keep these tips for good posture in mind:

• Stand up straight and tall.
• Hold your chest high.
• Keep your shoulders back and relaxed.
• Keep your knees slightly bent. Don't lock them.

When you stand, use a comfortably wide stance for the best balance. If you must stand for a long time, rest one foot on a low step stool. This eases the strain on your back. Take time for frequent breaks too.

It's also important to sit with good posture. Choose a chair that supports your back. Or place a small pillow behind your lower back. Some stores sell lumbar support pillows and cushions designed to support the back while sitting.
