He's generally happier about walking than he is here, I promise.
Edie doesn't particularly care that Marty is walking except in that it takes attention away from her. If either Tamsen or I are holding Marty by the hand and walking him around, she'll immediately shout, "I want to walk too!" and run to grab our hands. My compromise is to let her take his other hand so the three of us can walk around the house together, except Edie doesn't really understand that Marty's top speed is about 0.001 mph, while she likes to run around at top speed pretty much everywhere. (She has a ridiculous number of bruises on her legs that I'm pretty sure are from crashing and tumbling into everything.)
She still loves to play her board games. Here she is absolutely schooling me in Hi Ho! Cherry-O! this afternoon. Let it be known that she beat me twice, completely clearing her tree of cherries while I was left with my full complement of ten. Sometimes, it's a little discouraging having to compete against what is clearly a board game prodigy.
