i agree with you on teaching a child how/when/why to doubt something
i just dont believe theres any value in teaching a child how where and when to lie. Or keep secrets. i think its damaging to the kid individually and yalls relationship.
First of all, the point of breaking down the value of lying to a child that is ready to comprehend such things is to actually have true transparency and strengthen the relationship. The generation before mine in my family were not raised with such transparency and they all fell victim to some kind of predator or circumstance that could have been mitigated by not keeping secrets.
I put early emphasis making sure my kids never felt the need to keep secrets from ME. Now out in the world, especially as a young adult is different. Just knowing when to doubt isn't an actionable step. Telling a man you have a boyfriend when you don't to get him to leave you tf alone is.
As a parent, it's a must to remember that you are raising ADULTS to be.
