hello, ballerbaby1265. i would say that the child has had a concussion due to the fall and their symptoms. 60 beats per minute is normal in a child that is sleeping, but not while awake. two of the main symptoms of a concussion after are both sleepiness and being tired. i hope i have a great night.
