Love bites.

My son always has to have something in his mouth. When he's propped up over my shoulder he is constantly chewing on my shirt or my skin. I don't mind; it tickles a little and it's soothing to him. Yesterday he was chewing on my shoulder and it wasn't until I had slobber all down my arm that I realized he had left me a little love bite. =) Better my arm than on my neck I guess!
