bridge pose
Find an open space, either on a carpet or on a yoga mat. Lie on your back next to your child. Bend your knees, and slide your feet toward your bottom. Keep your feet flat on the floor, your arms on the floor alongside your body, and your fingers towards your feet. Keep the palms of your hands facing down. Take a deep inhale. On the exhale, press your forearms into the floor and raise your hips up off the floor. Hold the pose for five deep inhales and exhales. Try challenging yourself on the exhales to raise your hips even higher. Be sure to press your feet into the floor as you hold the pose. Slowly lower your hips back to the floor.
Try two or three more rounds with five deep inhales and exhales.
