Jia has the stairs mastered.

I'm so afraid that one of the kids will leave a door or gate open.  Our house is three stories, so two sets of stairs to worry about.  We've been working with Jia to approach the stairs slowly and turn around to go down.  She's got it!  It's sooooo cute.  Not that we don't still watch those stairs!  Now we at least know that if one gets left open she does know how to go up and down them fairly safely.
