<s>[INST] baby was standing upright, lost his fotting (barefoot) fell straight backwards on the back of his head full force on a wooden floor, I picked him up put cold water on the back of the head and a bag of frozen corn washed his face. He screamed for a while and sobbed then I wached. He ate fries. I watched him for 3 hours he was playing and running and coherant. I still cannot forget the noise his little head made. woke him up every two hour and he went back to sleep. Should I know more. Are there symptons one should watch for . [/INST] Hi.... I appreciate what you have done after injury. You have done all what can be done and that too very well. As you have asked for the danger signs of head injury which you need to be on the lookout for these are the ones - 1. Altered sensorial or incoherence2. Seizures or fits.3. Blood in the nostrils or any ears4. Watery discharge from nostrils or ears5. Continuous incessant vomiting6. Double vision these are not there you need not worry about this trivial head injury.
