Seizures 😔

My son has had seizures since he was born. He stops breathing for around 15-30 seconds and becomes unresponsive for up to a minute. His brain scans looked normal for his age so we're not sure what's causing them. He's 8 months old and I know for sure it's happened at least 7 times, 2 of which were within a week of him being born. I just want to know if this has happened to anyone else's baby? What caused them? Did they get better?
