My 2 year old son fell and hit his head on the corner of his bed right above his right eye. I could tell by his cry that it was serious. He had a pretty good sized bump come up and a gash on his head. My husband held an ice pack on his head and the knot has went down quiet a bit. And we cleaned his gash out, put some neosporin and a big band aid on it. I was just curious as to how long I need to keep him awake after bumping his head??
