I had a gastric emptying study done about 3 years ago and was SHOCKED at the results. I had been having what they thought were gall bladder problems. I had lousy weight gain, very troubling bloating, and just felt all around crappy and we couldn't seem to figure it out.
How the gastric emptying study works is that they have you fast for a certain period before hand and make sure your gut is really cleaned out. Then they take an x-ray of your empty stomach. Then they feed you either an egg-salad sandwich or a peanut butter sandwich (choose the egg-salad, the other tastes like rubber!) that is laced with a tracer they can see on the x-ray. They continue to monitor you every half hour and take a picture of what's going on as you digest the food. My results showed that I was delayed in emptying by nearly 2 hours! That explained why I got so incredibly full and why my enzymes didn't seem to work.
Here's how I changed things as a result:
-started taking my enzymes a good 10 minutes before a meal
-ate smaller, more frequent meals to prevent bloating and discomfort
-made sure to chew my food thoroughly (I often just snarf it down because I have other things I'd rather be doing than eat a 1500 calorie meal)
One we figured out what was going on, we were able to make positive changes. The delayed emptying would also wreak havoc with my blood sugars (I was on prednisone at the time.) I would test myself and give the amount of insulin appropriate to the meal I was about to eat, but the insulin got into my system well before my food was absorbed, so that resulted in the "timing" of the two being way off.
I hope you find a good solution. Also, as a seasoned pro with babysitting, it's been my experience that 4 year olds will say they're full when really all they want to do is go do something else. Perhaps if you make sure some high calorie snacks are available, even if your child takes a few bites throughout the day, there's a chance it could add up to a full day's worth of calories. It's frustrating, I know. Hang in there, and let us know how it goes.

Em, good luck on your test as well. I hope it yields a solution for you.
