Oaklen has two favorite things.
Animals and water.
You can always see a smile on that boy's face if you give him one or the other.
When I went in the backyard to water our (wild) garden and trees, he insisted on holding the hose. The water was freezing cold but he didn't mind getting wet. He kept hosing his face down every time he wanted a drink. Instead of freaking out he would be right back at it.
