Encouraging daughters to wear Hijab
Please could you tell me at what age a girl should be encouraged to wear hijab or at least cover her legs? I do not want to burden my daughter by making her wear hijab in Primary School, but should she wear it in order to get used to it? Also is it acceptable for a 7 year old girl to take swimming lessons in a mixed class, if she wears a wet suit covering her legs to the knees? Jazak umAllahu khayr
