B.C.
Was the surgery last week (Jul 26)?
The surgery is over and I'd follow the doctors recommendations for recovery.
I think I'd be a little more nervous leading up to the surgery than afterward but that's just me.
The stitches should heal up fairly quickly (that should make hair washing easier).
Does she have to wear a helmet to protect her head for awhile?
I'd stay in close contact with her doctors office and I'm sure they'll be happy to answer any questions you have.
It's hard, but try to relax for your child's sake - they can tell if you are upset/worried and it can make them scared.
If up coming school has you worried - work with the school and your doctor to make sure she'll be alright.
It's not likely the school will allow a child who's just had brain surgery to take gym/recess until they get a go ahead from the doctor.
