Thank you for your query.
is following injury
to the brain and this is not the case with your daughter.
Following a nose bleed a scab forms at the wound which can dislodge and cause fresh bleeding. It is advisable not to blow the nose and prevent the child from picking the nose. Kindly apply bland ointment or glycerine/coconut oil over the scab. In case bleeding persists then nasal packing has to be done by a ENT doctor.
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
