Sit comfortably across from your child, either cross-legged or on your knees. Straighten your spine and wiggle your nose like a bunny. Make the sign of peace with both hands, then bring your fingers to the top of your head on both sides like bunny ears. Keep your mouth closed and inhale quickly through your nose 4-6 times. Then exhale a long, soft, drawn-out "sh" from your mouth. Do this three or four more times.
This is a great way to energize and to awaken your brain in preparation for knowledge.
