7 month almost 8 month fell off the bed

My baby fell off the bed today and hit her head. The flooring is carpet but she hit the end of the dresser and has two knots on her head. Took her to the ER they just watched her for an hour. She was very active while we were there. However I’m just still a concerned mom. Anyone else have this happen before? I know someone who’s baby fell and had a brain bleed so I’m scared.
