Going crazy!

Man o man this little man of mine is nutso. He won't stop climbing, standing and jumping off things and he's got so many bumps and bruises. I can't leave the boy alone for a second. Am I doing something wrong or is this just what kids do at this age? When is it going to stop? I'm worried he's going to break something (arm, leg, etc). I can't leave him alone at all now. And I've given in. I'm getting someone to watch him 3 hours a week. Wow, so much freedom. What will I do with that whopping 3 hours of freedom?
