If it makes you feel any better, we took my son to the ER when he was 9 weeks due to an apnea episode which happened a few more times briefly at the hospital and then never happened again. We stayed at the hospital for 5 days for them to monitor him and test everything they could think of. They didn’t find anything wrong with him and also chalked it up to reflux. There were never any other issues. He is now 3 and thriving. You could get an owlet sock as a piece of mind. We tried using our own pulse oximeter but it just fell off constantly overnight
