honestly, in the best interest of the kid, you should take him just in case.
but note, there is a another dark side to this that you probably havnt thought of.
CPS, child protection services. They are ... well, were and sometimes are.. a good meaning organisation that helps prevents babies being dumped into dumpsters...
HOWEVER. they kinda go a little crazy.. a little to often. My mother in law used to do some papaer work stuff for them.. and she was litteraly shocvked at what little it would take for them to take your child away.
yeah, they can do it for almost anything, and brining a child with a head injury to the hospital could be taking the risk of some crazy CPS person deciding to take the kid away from your mom.
And honestly, if he is still mobile right now... the head ingury isnt that bad.. and having him takien from his parents is VERY bad...
so yeah,,, i would probably leave this up to your parents, there are some more factors in it than just making sure he is ok.
