In preparation to becoming a Big Sister

We brought Kate for a walk to the pool, where Ai Ai made tea for Kate from the pool water and bossed Kate to sit in her stroller.
This was Kate's "virgin" drink of water and her first time pee-ing - we'd never let Kate drink real water before, even though Kate was fully capable of doing it and pee-ing it out.
Ai Ai looked a little shocked that Kate was just pee-ing anywhere without asking to go to the potty! :P
