Send her to bed.

You hold your pretty niece tight until she manages to catch her breath and can look at you without her eyes crossing. When she manages a weak smile you pull her close and kiss her.

"Alright, that's all for now. You've had a long day. Go upstairs and get ready for bed and I'll come tuck you in."

She gives you a hug and slips off your lap, walking towards the stairs with a lot more confidence than when she came down them, even though she's a bit unsteady. You stand up to follow her, taking the tray with you, watching her slim body as she moves.

At the foot of the stairs she turns around.

"Thank you for teaching me, auntie Gina. I want to be a good pet for my mother and I know you can help me with that."

The she hurries up the stairs, and soon you hear the shower going.
