We are still waiting to see how Roscoe does on the high-calorie formula, compared to a combination of formula and milk. Subsequent tests have also indicated blood in Roscoe's intestines, so now they're trying to figure out if it's a fissure (small cut) somewhere in his digestive tract or if he is swallowing blood from a wound in his throat (with all of the tubes, it is a possibility). The doctor said she doesn't suspect a digestive tract infection (which would be a huge setback) because Roscoe has lots of energy, is handling oxygen well, and his tummy is soft.
Here's the big little man getting prepped for cares a few days ago. You can hear his music playing, which several nurses have noticed really calms him down when he gets fussy.
