The above structure is the actual Temple of Heaven (at the middle of the park where the retirees hang out.) Henry is comfortably napping in his stroller/car seat/plane seat/high chair. It’s called a Sit-n-Stroll and if you’re about to do a lot of travel with a baby, I’d highly advise getting one.
It has a lever at the back that you pull on to retract the wheels into the body to convert into a stationary (car/whatever) seat, that’s really easy to use. At one point, Karen and I did an inventory and Henry by himself required more luggage than the two of us put together. It would have been a lot worse had we not had this handy gadget eliminating the need for a separate stroller.
