So my 8 month old fell of the sofa again head first...

He cried right away... and went back to being the same.. the first time we took him when he fell they said to wait 8 hours and and nothing scary happens within those hours then he is fine... well this happened Sunday afternoon and yesterday he had a fever and it's gone today but hes been more sleepy and more serious he also has a bump where he hit his head at... I'm taking him to his pedi today.. I'm just worried they think I'm a horrible mom or ask me questions to why I haven't taken him in... I didn't take him in because he was his self for those 8 hours the ER doctor said to keep in mind... I'm worried for my son.. he is teething as well idk if that has something to do with his sleepiness and seriousness..
