Baby bumped his head

Hey guys. My baby was sitting up and was getting his hands out to start crawling but he got caught and bonked his head really hard on the kitchen tiles. He cried immediately. Hysterical crying. I rocked him and gave him the boob and he calmed down after about three minutes.

Can anyone tell me, should I keep him awake in case he has a concussion? How does that work exactly with a baby? He’s playing and smiling and talking like normal again.
