Leo is regulating his temperature

Today when I got to Leo's room I didn't see the nurse for almost 30 min.  (That's not very typical, they are usually quick to come say hi.)  It gave me time to really look at all of his environment and stats.  I noticed his temperature monitor was turned off.  Later the nurse explained that they turned off the temperature control function of his isolette incubator.  The isolette was controlled by a temperature monitor on Leo, causing the bed to go up and down in temp based on what was needed to keep Leo in temperature range (goal = 36.5 deg C).  Now the bed is set to a constant 28 deg C and Leo is regulating on his own.  Also, instead of always knowing Leo's temp, now his care team only checks it every 3 hours with a thermometer placed in the arm pit.  This is one of the three criteria for Leo to sleep in a bed without a lid. (1) show ability to self regulate, (2) gain weight for 5 days in a row, (3) weigh at least 1700 g (3lb 12 oz).  The plan is to pop the lid off his bed tomorrow officially when he is 32 weeks gestational age.

This change caught me by surprise.  I have only been to the hospital a few days over the last two weeks to avoid getting Leo sick with my cold.  At 32 weeks he should still be in sensory deprivation in the womb.  It feels unnatural to me for him to be exposed to lights and sounds for the whole day.  I'm not ready for him to make this change.  I still want him protected under his lid and cover, but I don't get a say.  

I held Leo for almost 4 hours today since we have a lot of missed time to make up for.
