Guilty Mommy

We took Corban outside tonight and brought up his bubble mower... he absolutely loves it! What started out as a very nice evening thought turned out very badly. He had crawled up on the porch, but was going back down into the yard. I saw him head for the step and was telling him to sit down and was headed to him, but before I got there he had tried to walk off the step and landed on his face on the concrete sidewalk. He's got a huge scratch and bump on his forehead, a scratched nose, and a scratch above his lip. I feel horrible - and he looks horrible.
