question: Hi my 2 year old son fell asleep very quickly after a slight bash to his head and never normally falls asleep that quick, I picked him up and normally he would wake up and stay awake after that but he just fell back asleep then I tried to wake him again and he wasn t responding I tapped him, tickled and blew on his face and nothing, I got really scared he was still breathing normal pace and after about 10 miniutes he then woke up and has acted his normal self since (1hour) what happened to him and why would he not wake when he s normally a very light sleeper?
