Update

Joshua was stable overnight, no signficant change either direction. His repeat chest xray confirmed that he has pneumonia. Therefore, we are almost certainly looking at at least 7 days here on antibiotics, regardless of whether he improves quickly or not. We're still waiting for his respiratory status to improve, as he continues on oxygen and CPAP. He is being fed via a tube inserted from his mouth to stomach, combination of formula and breast milk, plus IV fluids. Probably the bacterial infection set in while still in the womb from the normal flora that is in every womb, and once he came out and started breathing on his own, the pneumonia had a chance to get worse.
We still wait and pray, and trust the Lord. Thanks to Him for some rest for both of us last night. It had been an extremely rough night and day. Thanks also that everything post-partum for Sarah has been fine, and her pain has been very manageable. She is being an outstanding trooper, despite the disappointment of not being able to hold your newborn in your arms. We are able to sit by his side and touch him in his incubator as much as we want, which is a great blessing as well.
We continue to request and covets your prayers. We trust His promises in Romans 8 and 2 Chronicles 16, and believe Him to be working this for His glory.
