I don't know if I'm just really stupid, but I've tried a million different strategies and always end up unable to get up or down the stairs without shrinking the wife back down again. How am I supposed to do this?
You need to check out the closet in the master bedroom upstairs. Avoid getting too big before you head up, so she can make it.
That did the trick! I'd been going there too soon and not revisiting that closet. Thanks!
