A few hours ago I was holding my 8 day son in my arms and swinging him to let him sleep. I noticed it was helping him close his eyes so I did a quite fast swing (for just 1 second) and he almost immediately fell asleep (but woke up 10 min later).
I'm now extremely worried. It's been 5 hours now. The baby seems to be fine (eats and sleeps and was awake for ~2 hours) but I'm worried I might have hurt him.
Is there a probability I might have hurt him? If something has happened to him, how and when will it show up?
