Hello my two year old son was playing at his grandparents. He leaned over too far forward and hit the left side of his forehead near his hairline. Its a bruise a out the size of a quarter now. Well its 2 am and he wakes up throwing up. Is this something I should call in about or take him in over? He s now acting fine with no problems going back to sleep .
No need to worry. Sometimes, forehead bruise may be big in child Chat Doctor.  Just some painkillers have to be given. Gradually, it will become bluish black and soft and subside. It may sometime take 10-15 days to resolve fully. Nothing to worry, until the child develops altered mental status, recurrent vomiting, severe headache, seizure or bleeding from ear, nose or throat and the bruise goes on increasing in size.
