Not that I want to give her help, but I think Amber would find it more enjoyable to walk outside than marching inside the gaycare living room waiting for the (snack) bell to ding. If she, oh I don't know, walked from the house to the family dollar and back, I think she'd find the whole experience more enjoyable at least. If she's afraid of falling, have Becky carry a sturdy chair along with her.
Sure, she'd being walking right to a store full of shit food, but this gorl is gonna eat little debbies on the sly anyway. She might as well work for them.
