One week later...

We can hardly believe it has been a week since Caleb was born! He has made great strides in the last week, but today has been very challenging for this momma and Caleb! Caleb's oxygen need has been sitting around 35 the last couple days, but for some reason, today it has gradually gone up and up and up. When I left him earlier this afternoon he was up to 75!! He has not been that high since he was only 24-48 hours old. They have called in the cardiologist who ordered an X-ray to make sure something wasn't brewing in his chest. Nurse told me that looked pretty clear, so not sure if we are looking at a cardiac problem now or whether his body is not handling the increased feedings very well or what is going on. Something is certainly 'stressing' his system today causing him to need a lot more oxygen. :( Will keep you posted if I hear from the cardiologist or nurse this evening about what might be going on...
