> allowing them the freedom to do whatever they want and then telling them afterward that none of the consequences are actually their fault and they can at any time walk away from anything that makes them feel sad or scared or overwhelmed is not the way either.

Those things are *not* the same as validating their emotions. That's *not* what that means.

If my toddler is crying because he doesn't want to go to bed, the conversation isn't: "Oh, I understand you want to stay up. Okay, let's stay up later!". Instead the conversation is: "Oh, I understand you want to stay up later. You're having a lot of fun now. But, hey, you'll get to play more tomorrow. We need to go to bed now, so we can be rested for tomorrow.", and then we go to bed.

That also isn't part of validating someone's emotions. When my toddler is standing on something wobbly, and then falls the conversation isn't: "ow! That looks like it hurts! I'm sorry buddy. But don't worry, it's not your fault." the conversation is: "That looks like it hurts! I'm sorry buddy. Hey, did you notice how wobbly that thing you were standing on is? Next time, we need to be more careful about what we're standing on so we don't fall. That way we won't get hurt again".

Validating emotions is precisely about getting them to a headspace where they are able to hear your reasons why they have to do a thing they don't want to do, or hear you explain the consequences of their actions. It's exactly the opposite of letting them do whatever they want, and it's exactly the opposite of telling them the consequences of their actions aren't their fault.
