My son went through a few phases when he was eating literally more than I was! He was hungry all the time. It drove me crazy, to be honest.
A few things that helped us:
* Give her a Really Big lunch. Moving the big calorie load earlier in the day will help her digest it a little more efficiently, and also might help prevent hungriness that looks like stalling.
* I got this from a mother of four: pasta with alfredo sauce. It's very fatty and fills them up faster. Fruits and veg just don't have enough calories.
* smoothies with protein powder. see above
Good luck--it does end, I promise.
