How did Boyd grow up so fast?

 No help needed to pedal his trike (even up the hill). Next summer it will be on to the bike with training wheels.

 Mountain climber. New confidence during scrambling adventures.

 Playing in the trees.

 Water man. You will get soaked.

 Yes, he can put his face in the water.

 Fun times with Mimi.

 For a Father's Day treat. Boyd had pizza and rootbeer with Dad (Mom does not allow soda). Here he was clapping because he was so excited.
