Is That Logical, Kid?

Ok I just want to start by saying these are my personal opinions and experiences, and I am in no way professionally trained on the discussed topic. I love the logic in a child's perspective. My 4yo daughter went outside, without mittens on. (typical) What was the first thing she does? She grabbed a big handful of snow. She told me her hands were cold and she wanted to wear mittens. So we get to the car and she finds a fair of fuzzy finger mitts on the floor that car cold and soaking wet. I told her they would make her hands even colder. She grabs another pair of her gloves that are also wet from playing outside all afternoon. She thinks that her hands will in fact warm up if she wears these freezing cold, soaking mittens. I find it so cute how simple her logic is. Put mitts on, hands will be warm. Not even taking into account that the mittens were cold and wet already. 

When she is hungry she thinks if I let her have a single gummy bear that she will be full. I love that she thinks anything she eats will fill her tummy. Why not eat a piece of fruit or the meal I just gave to her. 

USUALLY, once I explain the reasoning to her she understands my perspective and goes through with the more logical response. However, when she is experiencing a meltdown, all logic is thrown out the window. You give her the gummy bear, or the wet mittens and let her learn for herself. Sometimes it makes the meltdown go away, but sometimes it just makes the whole thing worse. The great thing about kids is that its a roll of the dice every time.

 I wonder when/if adults ever have a full understanding of logic and when it sets in. Do you think we ever fully know what the most logical path is, or do we still sometimes have a tantrum and just do what we want? If I get cold would it be more logical to get a blanket or sweater, or just to turn up the thermostat? Or are they the same? Both will achieve warmth. If I say I'm hungry, it would be logical to prepare a meal for myself, but sometimes I grab a bag of chips and then I'm still hungry and prepare the meal anyways. I don't know if we just go through life with our version of logic, and doing what we think is the best route. I don't think we are ever fully aware. We should give kids more credit, they are smarter then we think, and doing the best they can, just like we are.
