Why do Muslim parents make their children wear hijab?

It is not because Islam asks little girls to be covered. In Islam every action is accounted only once he or she is matured and little children are free from laws. Normally Muslim parenets couch their children to learn Islam in practical way at very young age as 7~10 to pray, to be good and kind to others, standing up before elderly & teachers, to be honest and not to tell lies etc. I myself sent my daughter to school in their normal uniform. But her mother wears for her a scarf whenever we visit a mosque and she loves that. It is all as a part of moral couching to bring them up according to a faith in which each parent believe as best and will be best for their offspring. I think true Christians also do the same couching to bring them to be true Christians . Parents only can guide their offspring, but it is upto them and they have their freedom of choice to be honest practicing Muslim or anyother once they are grownup.
