My family had been trying for months to teach my nephew how to walk when he finally did it. He had stood up a few times before, but he hadn´t been able to take a step just yet. Today, after we had been playing on the floor all afternoon, he suddenly stood up. To my surprise, by the time I got my cellphone to take a picture of him, he had already taken three steps to grab a toy. My sister was sad that I hadn´t filmed the event, but I will never forget it.
