To what extent can gender stereotypes be harmful for children?

Gender stereotypes has a an affect on kids to a great extent.

Explanation:

Many experts say that while a girl is growing and developing she should have a male role model from a very young age, and even while she grows up. For boys they should have a mother/female role model. If the child were to have only one parent their perspective would change/shift. Whatever they are showed or told to do it would effect the way they were to do something in the near future

Children are very impressionable so what ever is portrayed in front of them, they will follow.
