Thanks everyone for your help and get better wishes for Emma.
She threw up at least 1 more time in the middle of the night

At least this time she was courteous

and got out of bed to throw up on the rug that I can wash. She actually let me sleep until 6:45 which is UNHEARD of for her-she usually wakes me up at 5 because she wants breakfast-so obviously she's not her normal self.
She is actually in a very good, cuddly, and even sometimes playful mood, so I think she may be feeling better. She wanted to eat when she woke up, and I don't have any yogurt in the house (I need to run out and get some in a bit). I made a little oatmeal, and fed that to her with some hard-boiled egg (just the white), and a little mashed banana. She ate it right up.
She hasn't thrown up again, but I have heard her kind of gulp like she wants to...I'm not sure she's quite all better yet. I'm going to run to the store today and get some yogurt for her, and hopefully that will help.
She's wrestling with Milli right now-I think that's a good sign.
