We had so many days that Chad was outside working before the kids and I even woke-up and he'd still be going when I put the kids to bed. I helped him as much as I could while our kids hung around and "helped" as much as they could.
Bryce especially loves to be outside with Chad. After awhile Caden would usually wander off to find a friend, but Bryce would stick it out.
And when he needed a rest, he made do with any spot he could find.
