That's one heck of a walk, especially when you're done and you have to get back to the car. I've seen carts with fat tires for sand, those plastic toboggans / terrain sleds would work for both sand and land, and of course frozen lakes if you're into ice fishing.
You know, we've all been sleeping really well... Not like six hours straight, but the (cluster) feedings are easy and relaxed because we co-sleep, minimal interruption to anyone's flow.
That, and I worked hard to insluate these few months so that our being together isn't in competition with anything else in our lives... We're here, we eat, we sleep, we learn, we love.
Yes, he's a Zen baby.
