There's this theory that we adults have when it comes to kids.
If we let them try something negative and experience the natural consequences, they will learn.
I know that works sometimes, but it's not a fail safe method.
If you let your child eat dirt or sand, they might not actually learn that it tastes terrible and they shouldn't continue.
And while I'm on the Judah video kick, my very favorite Judah time right now is when we're both on the floor playing together and he is giggly and interactive. Love. This is a couple months old now, but you get picture.
