When will Mariam wear hijab as my daughter is the same age as her?

Mariam does wear hijab most times out of the house, as she wears hijab to school, for example. In the videos you often will see her without hijab because we film in our house and I want her to be in a natural environment. I want parents to see exactly what it is like teaching children in their natural environment, and children will not be wearing hijabs inside their own home. It may make the children react differently and it would not be realistic, and I wanted something to be realistic that parents can relate to. I completely appreciate there will be a second view that people would want to see her with a hijab all the time, and I completely appreciate that, but my reasoning for her in the videos where she does not have a hijab is because it is not obligatory on her at this point in time and because I want it to be natural in terms of the videos and how we as parents relate to our children indoors.
