ex.ex.expat... hitting with 'enough force' would be an assumption.... if struck with appropriate force at the right spot on that part of the head can kill anyone even a grown up like me and you...she was just a tender 5 yr. old child.. may be she could not bear those many hits... but since the mother was trying to teach her something IMO she wasnt trying to kill the child... if the intention was to kill she need not be teaching her... she can just hit her once with 'énough force'...:)
