Yes, it’s absolutely worth it. I used to work in a group home where 10 teenage girls lived. These were children who were/are in the custody of Child Protective Services. I used gender neutral language with them and eventually some of the girls who had lived there for a longer period of time adopted this language and encouraged others to use it too. It’s necessary to model. Remember you are a bigger influence than you give yourself credit for.
Awesome! I think just a few moments of thought can help us use language that is not unnecessarily gendered. I always say that this needs to start when kids are really young, so I’m so glad to know that at least one teacher is heading in the right direction. Keep it up!
