My two older children have had this too. Also directly related to being sick. I wouldn't panic! If you want to go to the dr., go. It's always better to be safe than sorry, and it will give you peace of mind. But, if you wait it out a couple days and let her body regulate, it will stop. Being sick like that is hard on the body, and it completely empties you out. The idea that the emzymes aren't making it to the digested food makes a lot of sense. She'll be fine.
