Thank you for your prayers. They've had to raise his supplemental oxygen to 4 lpm in order to keep his oxygen at 90. Yesterday he only needed 1 lpm. (Liter per minute). Please keep him in your prayers, also [ray for the 2-year-old in the same room with him (who cried all night). They think they both have asthma and some unknown virus caused an exacerbation. (I don't understand the wisdom of putting two little guys with unknown viruses in the same room.)
