Sleeping

If you are worried it’s always best to get them checked out. Especially if they seem drowsy and harder to wake up than usual.

Id take him to the er. I always tried to keep my son up after a hard fall. Especially if nap time was near. I hope he’s alright 💕

Do you have an urgent care clinic instead of waiting at the e.r.? I’d probably get him checked just to ease my mind, it could also, coincidentally, be a growth spurt so he’s needing more sleep?

I would get him checked to be safe and put your mind to rest, nobody should be allowed to sleep after a bang to the head if it’s not usual for them as it may be drowsiness from the fall instead of tiredness although if it was a few days ago, he’s probably absolutely fine.
My older son fell on the stairs recently and said he was fine, we took him to a&e anyway and he’d broken his wrist. If we listened to him, we’d never have known as he carried on as normal! Kids are so resilient but it doesn’t ease the worry and mum guilt!
