sounds like Gastro to me babe.

We have just had a round of it through my household and it is soooo gross. My boys were all fine except for the spewing and unable to keep anything down but it didnt last.
As long as she is feeling a little better today and is starting to keep stuff down then I wouldnt stress too much.
Be warned though the other may start too

It is horrible when your babies are sick and you cant make it better for them but hopefully she is on the mend now.
