Geez... I hope the news from OSU is different. In terms of choices, I've faced that same decision several times and it's always difficult and guilt-producing. You know your boy the best and will take into consideration all factors. You have my full support and understanding for whatever path you choose, as it is a decision made out of love. The idea about using a sling, especially for stairs is a very good one. Holding Abbey in my prayers for much more quality time with you.
