My 6 y/o had femur surgery and just had her cast off on Monday. We are leaving for vacation next week. She's not walking very well at all yet and I'm thinking we're going to need a wheelchair for her. We've got her heavy hospital grade one at home, but there's no way I'm bringing that beast with us. I'm looking on amazon at the lightweight chairs, since we'll prob need it for the airport too. Does anyone have any recommendations? There's a bunch to choose from. I'd love the smallest one to make it easier to collapse on the busses but I'm worried the small wheels won't maneuver as well outside. Any thoughts?
