She wants to be babied.

It takes very little energy to compel the staff in the daycare to want her out of her big girl clothes and into something more "age appropriate." This was not the first time she has been in this daycare, and odds are it won't be the last, so she had left the proper supplies necessary to enjoy herself here the last time she came. One of the daycare ladies suddenly remembered where it (in this case, a large dufflebag full of adult diapers) was and brought Natalie into the middle of the room.

Since the changing table was built for actual babies and toddlers, she was instead instructed to lie back on the massive foam matte in the middle of the floor meant to look like a giant jigsaw puzzle. She retrieved the baby oil and baby powder and applied it to her own naughty place and before she knew it, her legs and butt where elevated and an unfolded diaper was slid under her.

The lady congratulated herself on a job well done after strapping her diaper into place. Natalie decides that she would rather only wear her diaper and nothing else, her modest breast size juxtaposing the childish garment beneath her power-induced glamour.
