Edit: she checked out fine. Even gained a few ounces- wtf? My milk is actually heavy cream apparently...lol. And she was hilarious with her silly active playfulness all evening:)
So the doctor's office finally called back. They sent us back to the ER, who kept us three hours then sent us home. The snarky highlight of the day: the nurse who tried to get us to pop her off the boob to take a popsicle, because "we need to get more fluids into her," and my milk, apparently is what? a solid? gas? sand from the Ghobi Desert? (Gwen & everyone, that's so not a slam on the popsicle idea- it is a great plan, but she's having none of it. The timing/wording was just hilarious.)
At any rate, she wasn't really dehydrated and she's kept her nummins down all day. We have a check up tomorrow afternoon but hopefully things are back to normal, or at least SNAFU/toddler normal.
