Yep, Maddie will do that nightly if I don't give her yogurt every day. I give her about 2 tbsp of lowfat plain yogurt everynight at around 9pm and problem solved. If I even skip one evening on the yogurt, it is pretty much a guarantee I will be awakened at 2 or 3am to her puking up bile. Not too much fun to wake up to! :?
