When my son was 2 weeks old I thought I saw a large pause in his breath, I took him to the hospital and they monitored him, ran the ph test and said he showed no signs of apnea or reflux. They put him on the apnea monitor for safety precautions. Now, all the sudden, he alarms constantly with low heart rate, and apnea episodes. He now has central apnea. Can this come out of nowhere?
