Is there anything better than the sound of little people laughing? Every time I watch this video I have to join in. Milo is the most amazing big brother in the world and will do just about anything to make Lucy giggle. And Lucy is the most doting little sister you'll ever see. There is nobody in her world like Milo. Don't get me wrong - they know exactly how to push each other's buttons (especially lately), but most of our days sound a little more like this, which I personally think is pretty near perfect.
