your daughter is blessed by having such good, understanding parent. Good father- daughter bond is very important for her.
she will go though this difficult time with your care and support.
Is there something else may help her besides love and care?
Such as doing sports, participating community volunteer work. Joining cheer-leader team ( high school has it, it will put her into popular girls circle).
learning make up, shopping with her mother for some trendy clothing.( Mother- daughter bond ).
Girls are sensitive of their image at this age. I know she is a beautiful girl, but doing make up should start at teenager's year, it can become an habit and life style later on.
M daughter is required by me to have little touch up at morning when she start middle school this year. even if some Chinese mother told me: she already has beautiful features, she does not need it"'.
good habit and good taste need to be cultivated at young age.
one more thing: Hu*****and and wife communicating with letters is very sweet, especially after many years of marriage ,living under one roof.
