No judgement please

Woke up in the middle of the night to nurse my son, accidentally fell asleep with him in my arms. That was around 4:30 and I woke up again at 6:30. I have a down comforter so while it’s thick, it’s light and airy but I woke up to it covering my son. 😭 he seems to be fine, he was a bit hot but other than that he was breathing. I just fed him, changed him, and now he’s in his rock and play. Seems totally normal but im still worried. Could I have hurt him? I’m not sure how long the blanket was covering him but I know he was breathing. Idk if should call an advice nurse or something for peace of mind.
