Last night while the older girls were at mutual and the middle kids were playing with friends, Phoebe and I spent some time playing outside. She'd grabbed an apple while I was tidying things up after dinner and kept on munching it down to the core (which was a welcome change from her usual bite-and-discard-and-grab-another method of eating apples). She took it on a walk around the block and then carried it about as we played at home.
More than anything, she wanted some time in her car. She's figured out that she needs to keep her feet up if she wants to be pushed around by someone else, and she's figured out how to use her own two feet to push herself backwards (she loves travelling backwards and will often walk backwards just...to walk backwards), but when you're travelling by car, sometimes it's nice to move forwards.
Fortunately, we live on a rather steep hill and Phoebe discovered that if she goes backwards up the hill, gravity will happily push her down the hill (going forwards). She went up and down the hill several times, clever little girl!
