That is Atri's boot.
He has a "toddler fracture." (no really that's the medical term)
What did he do about it, you guys?
He ran in a field in Central Park and played tag with me and some very bossy big kids, dressed like a fireman, performed a puppet show, did yoga with me aaaand meticulously prepared me a picnic of plastic food.
I hope we all learned something here, you guys.
