Dads are definitely good for a different kind of play than moms are. Here the kids are using James as a human play structure as they run around, climb, and tumble down him. This is something I don't think I would've been ok with pregnant or not. But I do admire the kids' creativity for coming up with this little game on their own. And I love James for sitting there and letting them have their fun (like any good dad would) as they did this over and over again.
