CPAP free...

Is still the way to be. We're now on day five without a CPAP. He is breathing mostly room air (21% oxygen). Every once in a while he'll have a "de-sat" where the oxygen level in his blood takes an unexpected drop. But most of the time he pulls out of those on his own. As things stabilize, the next step will be dropping the airflow in the tube. It is still at 2 liters/minute.
Things are looking good!
