My daughter at that age was embarrassed as well. I just explained to her that she was young and all young children have same thing. I remember the first time she looked at her legs, she said "Omg, I am turning into Dad"... I started laughing and so did she. She eventually got over it and forgot about it. But everyone is different. How about stockings? Can she put stockings on? Tights?

Been there myself and unfortunately my daughter suffers from it too. Once I asked a skin specialist for a permanent remady and she told me that waxing at the age of 7 eradicated the problem 80% and after that you can continue but with miraculous results. You got to discuss it with her cause I did endup shaving my legs myself, the result is I am still suffering
