Just a quick observation from looking outside my window : snow! When there’s a foot or two of snow outside, navigating the outside world could prove REALLY troublesome, unless she has some serious ice climbing skills (and the makeshift gear, somehow?)
Although, now that I think about it, at such a light weight she could at probably walk on snow without sinking. I just don’t know how would she get her hands on shrunken winter clothing? Yeah, tinies are much safer inside the house, regardless of weather.
