A Day at the Park and OCD

First off, I hate this weather. It is almost 60 degrees out but the wind is horrible!!!! It totally tricks you! Yesterday Porter and I decided to brave the wind and headed to the park. I have a feeling we will be spending all summer outside, which, if you take a look at my child, you would agree he definitely needs that sun! Lately I have been noticing that Porter is a little Obsessive Compulsive. He freaks out when anything is on his hands. Even in the tub, he splashed the water and then hated that there was water on his hands! He hates things like cheetos and cries when he realizes what they have left on his hands. He fell down at the park, but it didn't seem to phase him until he realized he had dirt on his hands. When he thinks there is something on his hands, he rubs them and scrapes them and scratches them. What? How does this even happen? I am like the furthest thing from a clean freak and my child is seriously OCD. Any suggestions from you parents out there? Is this at all normal?
