NP. Mine is just 5 and has long hair that I do every morning and at night. She is free to get a cut whenever she is ready to. Right now she wants to grow it and it's a bit of a PITA for us, but not that big of a deal.
When I was a kid, I had short hair mostly and then grew it when I was 14-15. I didn't really know how to braid it nicely and my mom would do it for me every morning. Even after I learned it, it was our sort of ritual and she would make my hair and it was sweet. I remember that time very fondly. And I will teach my kid how to do her hair but also be there to help her as long as she needs.
Absolutely no shame here about this !!
