Thank you all very, very much for your comments, emails, phone calls, and prayers. We all three survived (of course) and things have already improved greatly.
She has officially transitioned to one nap and is fully walking too. Yes, seemingly small transitions are very big when you have only been on earth for 12 months.
Speaking of transitions, I thought I'd fill you all in on how well the muffin is advancing.
She walks: almost always, sometimes pushing stuff, often barefoot and outside (gasp!)
She talks: mama, papa, mono (her monkey), bye bye, wow, agua, brita (the neighbor's chihuahua), abu babu (what?)
She plays: outside usually, loading and unloading various containers, and flipping through her books
She likes: peaches, lying on her "fuzzy fuzzy" after her bath, teething biscuits (yes, I know), giving papa kisses, playing with mulch and rocks (don't say it), going to the park
