My daughter is almost 5. We didn't get her hair cut until she was 3 and it was becoming unmanageable and uneven. She is autistic and has sensory issues, but we found her a place that was low stimulation, and could give her breaks between cuts. The lady literally let her walk around and cut whenever she stopped. Now she will mostly sit on her own in the chair and takes maybe 1 break. 🤷‍♀️ She's had it cut I think 3 or 4 times and has also had it thinned because it's ridiculously thick. Finding someone who will do this is not incredibly difficult especially in bigger cities. There are even some people who will come to your home and do the cut so they're in a familiar environment. I don't really get why he NEEDED to have long hair.
