Talk to Pediatrician on Minor Skull Fracture

my baby fell from the bed on this September .he fell twice a day. after that he was having vomiting issues so he was rushed to the emergency. where his CT scan was done, in which doctor discovered that he has mild edema and small skull fractures on behind the head. basically he diagnosed him with the mild edema. but I am concerned about those Mild small fractures. Dr said these are normal in babies but how much time they take to heal because after all precautions my baby fall while playing or something. he hit his head but everything is normal till now . I fell really concerned even if he he hit his head slightly. Is he alright. it's been 5 month to his his mild adema. he was discharged after 1 day.
