Paranoid about Shaken baby syndrome from bouncer?

FTM and I'm up anxious right now thinking about how my 6 week old was put in a bjorn bouncer and when I wasn't looking, he was bounced in there kinda hard and I'm worried that somehow it could cause SBS. I looked up videos of SBS and it seems like it has to be violent but im so worried that somehow the bouncing could've been too aggressive because if his head bounced a bit what if that messed my baby up. 😭
