I wouldn't trust you either! Instead of waiting to see if the grandchildren are motivated, take forward action and ask them if they'll help because you're injured. There is absolutely nothing wrong with that and just because you don't want to look like you need help, you will probably avoid saying that. That is what family is for, to help each other. You might as well put it up there now and enjoy it for an extended period of time than wait until there's only a week left. I think it will be a boost for Lulu! Who doesn't love a little Christmas?
