Happy Halloween everyone!
First time trick or treating! He really is happy, but has a hard time smiling for the camera-usually he gives this uncomfortable grimace while declaring "cheese" with enthusiasm. Hopefully it will cool down a little, I made his costume out of fleece and it is pretty warm and snuggly.
ETA: We ended up visiting 5 whole houses. Then he laid down in our neighbor's driveway, so it was time to go home. And it never cooled down at all, the AC is on now.
