Swinging. There's only 1 swing and both boys could stay on a swing until they pass out, so we had to practice taking turns this weekend. Miraculously, no blood was shed.
Riding Chase's 4-wheeler (really a John Deere power wheels, but Chase thinks it's a real 4-wheeler). We brought Cole's John Deere power wheels tractor, but he insisted on riding Chase's because it didn't get stuck as often as his did.
Occasionally, the 4-wheeler would get stuck and Cole would have to hop out and push.
