When did your stutter start? Did it go away? Did it get worse or better over time?

When did your stutter start? Did it go away? Did it get worse or better over time? My daughters stuttering started when she was 5. It’s been more than a year now and I thought it was getting better and she started stuttering again but now, it’s prolongation. Just trying to gauge if it’s possible that she’ll grow out of it?
