Well it's not RSV, we know that. Tomorrow we find out if it's the common cold or the flu. We have an echocardiogram which is an ultrasound on his heart to see if there are any abnormalities there. If these come up negative then it's off to Primary Children's Hospital to meet with a lung specialist and perhaps run some other tests. If all of these turn up negative then he just breaths fast and it's a mystery as to why. Thanks for the prayers.
