Swinging, Sliding, Running of Ice Cream

So after our run to Moo's, we had to bring them to the park and let them run off the strawberry sorbet. Oscar loves swinging so much we spend half the time begging him to get down and do something else.
This is the conversation that always happens after fifteen solid minutes of swinging:
Us: "Do you want to go on the slide?"
Oscar: "No! I'm swinging."
Us: Do you want to go play on the wagon?"
Oscar: "No! Just swinging."
Eventually though he can be persuaded, with the help of Parker, to do other things like climbing and sliding.
