Proof is in the tube

Here is Maryam at dinner time munching on her favorite, Cheese Puffs! As you can see from the tube, she actually swallowed some! Hooray! I plugged in her tube and this is what came up! Orange stomach stuff! Hooray! PROOF that she's swallowing. Now, how do I get her to swallow more than just the cheese powder she sucks off of cheese puffs? That's the real challenge, I guess.
