We spent the day at the hospital.  Silas seemed well, if they hadn’t told me something was wrong, I wouldn’t have thought anything was wrong.  His vitals have been good.  They actually went  down on oxygen requirements from 4 liter to 3.5, and he tolerated that well so far.  This first Xray showed a lot of gas, more than normal but not in areas where it shouldn't be, so that's a plus.  They started suction from his gut and stopped his feeds, back on TPN (IV nutrition).  Another xray in the afternoon showed some improvement but still similar.  They are doing blood and urine cultures to check for infection but they are not starting antibiotics since they are hopeful it isn't something major based on how he is presenting.  Time will tell.  Thank you for your prayers.
