I wouldn't be alarmed at all hun. It might be though that she really doesn't want the food yet, in which case it wouldn't hurt to try going a few days without food to see how she reacts. Have you found that she's sleeping better at night now? If not, then that might also be a sign that the waking was not due to needing food. Just a thought hun. But whatever you decide, stay calm when she spits it out, and don't react. It is so easy to react just once, which then encourages the behaviour for months. GL.
