Joshua did great on the kidney ultrasound, they didn't see any abnormalities. The chest x-ray did find that his right lung is not developing at a normal rate. Joshua's rapid breathing (tachypnea) usually occurs during feedings and doctors said that it might be because of his right lung or its just a part of him.
The doctors also stated that his esophagus and the stomach are functionally normally, and he doesn't have any reflux (but can change). Joshua should be able to bottle feed without any problems but will need a feeding specialist daily until he can consumes the daily amount. Joshua's weight has increased to 7 lb 11 oz, due to the increase of oxygen and calories.
